Top 5 Reasons Java Developers should learn Hadoop?




What is Hadoop?
Hadoop is a free, Java-based totally programming framework that supports the processing of huge data units in a distributed computing environment. Its miles part of the Apache project sponsored through the Apache software basis.
Large quantity of data is being accumulated every single moment by organizations. To analyze those facts, they need tools and people skilled in using those tools. One such tool is Hadoop. With Hadoop, no data is large sufficient! Around 4 million entities were transformed to PDF by New York Times in just 36 hours the use of Hadoop. Huge data is almost a minuscule in hands of a technologist using Hadoop.

What is the Reason Java Developers should Learn Hadoop?
The foremost reason is, Hadoop is written in Java, and those developers who already have the expertise of this computer language can pick up Hadoop extra without difficulty than others. Java developers are at an advanced position in today’s marketplace.
             Ø  Hadoop is an open-source software framework for storing data and running applications on clusters of commodity hardware.
Ø  Hadoop works on less expensive servers enabling it to both store and process data. Because of this, it is also called Distributed Processing.

Ø  It is also called Parallel Processing because it enables working on multiple servers at a time.

Ø  Map Reduce programs are written in Java which is relatively easy to analyze and use.

Ø   Hadoop is a Game Changer:
            Apache™ Hadoop® enables big data applications for both operations and analytics and is one of      the fastest-growing technologies providing competitive advantage for businesses across industries.

Ø  Hadoop is a key component of the next-generation data architecture, providing a massively scalable distributed storage and processing platform.

Ø  Hadoop enables organizations to build new data-driven applications while freeing up resources from existing systems. MapR is a production-ready distribution for Apache Hadoop.

Ø  Businesses and Organizations are using Hadoop in the best possible ways, and are in a constant hunt for java developers skilled in Hadoop.

Ø  Hadoop has the ability to handle all types of data (from disparate systems) such as server logos, emails senor data, pictures, videos etc.

Ø  The creation of SQL-on-Hadoop options will further enhance usability& adoption.

Ø  The Data Market will likely the fastest growth are Hadoop and No SQL software and services.

What are the Demanding Situations of Using Hadoop?



What are the Demanding Situations of Using Hadoop?

Many organizations are adopting Hadoop in their IT infrastructure. For vintage huge facts staggers with a sturdy engineering crew, it is usually now not a big problem to design the target device, chooses a generation stack, and begins implementation. Those with a variety of experience can nonetheless every so often face boundaries with all of the complexity; however Hadoop beginners face a myriad of challenges to get began. Under are the maximum commonly visible Hadoop challenges which Grid Dynamics resolves for its clients.

Diversity of Vendors, which to pickup?
 The commonplace first reaction is to apply the unique Hadoop binaries from the Apache website however this outcomes in the attention as to why only a few corporations use them “as-is” in a production Environments. There are quite a few wonderful arguments to not try this. however then panic comes with the realization of simply how many Hadoop distributions are freely available from Hortonworks, Cloudera, MapR and finishing with huge industrial IBM InfoSphere BigInsights and Oracle Big Data Appliance. Oracle even consists of hardware! Things end up even more tangled after a few introductory calls with the carriers. Choosing the right distribution isn't a smooth task, even for experienced staff, due to the fact every of them embed extraordinary Hadoop components (like Cloudera Impala in CDH), configuration managers (Ambari, Cloudera manager, and so on.), and a normal vision of a Hadoop mission.

Map Reduce programming is not a good match for all problems:
 It’s good for simple information requests and problems that can be divided into independent units, but it's not efficient for iterative and interactive analytic tasks. MapReduce is file-intensive. Because the nodes don’t intercommunicate except through sorts and shuffles, iterative algorithms require multiple map-shuffle/sort-reduce phases to complete. This creates multiple files between MapReduce phases and is inefficient for advanced analytic computing.


SQL on Hadoop:
 There’s a widely acknowledged talent gap. It can be difficult to find entry-level programmers who have sufficient Java skills to be productive with MapReduce. That's one reason distribution providers are racing to put relational (SQL) technology on top of Hadoop. It is much easier to find programmers with SQL skills than MapReduce skills. And, Hadoop administration seems part art and part science, requiring low-level knowledge of operating systems, hardware and Hadoop kernel settings.

SQL on Hadoop. Very popular, but not clear:
 Hadoop stores a lot of data. Apart from processing according to predefined pipelines, businesses want to get more value by giving an interactive access to data scientists and business analysts. Marketing buzz on the Internet even forces them to do this, implying, but not clearly saying, competitiveness with Enterprise Data Warehouses. The situation here is similar to the diversity of vendors, since there are too many frameworks that provide “interactive SQL on top of Hadoop,” but the challenge is not in selecting the best one. Understand that currently they all are still not an equal replacement for traditional OLAP databases. Simultaneously with many obvious strategic advantages, there are disputable shortcomings in performance, SQL-compliance, and support simplicity. This is a different world and you should either play by its rules or do not consider it as a replacement for traditional approaches.

Full-fledged data management and governance:
 Hadoop does not have easy-to-use, full-feature tools for data management, data cleansing, governance and metadata. Especially lacking are tools for data quality and standardization.

Data security:
 Another challenge centers on the fragmented data security issues, though new tools and technologies are surfacing. The Kerberos authentication protocol is a great step forward for making Hadoop environments secure.

Secured Hadoop Environment. Point of a headache:
 More and more companies are storing sensitive data in Hadoop. Hopefully not credit cards numbers, but at least data which falls under security regulations with respective requirements. So this challenge is purely technical, but often causes issues. Things are simple if there are only HDFS and MapReduce used. Data-in-the-motion and at-rest encryption are available, file system permissions are enough for authorization, Kerberos is used for authentication. Just add perimeter and host level security with explicit edge nodes and be calm. But once you decide to use other frameworks, especially if they execute requests under their own system user, you’re diving into troubles. The first is that not all of them support Kerberized environment. The second is that they might not have their own authorization features. The third is frequent absence of data-in-the-motion encryption. And, finally, lots of trouble if requests are supposed to be submitted outside of the cluster.

 Conclusion:
 We pointed out a few topical challenges as we see them. Of course, the items above are far from being complete and one could be scared off by them resulting in a decision to not use Hadoop at all or to postpone its adoption for some later time. That would not be wise. There is a whole list of advantages brought by Hadoop to organizations with skillful hands. In cooperation with other Big Data frameworks and techniques, it can move capabilities of data-oriented business to an entirely new level of performance.


Top 6 Reasons Why PHP Better for Web Development?



Top 6 Reasons Why PHP Better for Web Development?
PHP is a programming language used for creating dynamic websites. Currently received statistics endorse that over 20 million active web sites are the use of PHP. It truly is not all; its use is discovered in over a million web servers. PHP is known for its ability to optimize memory. As a result, it never allows server overloading. Instead, it helps in improving a server's processing speed significantly.

There are several reasons why the majority of the people and companies looking for web development service are opting for PHP website development. This programming language makes the process of custom net improvement easier. Further, the language can be acquired from several open source development structures along with Word Press, OS trade, Joomla, Zen Cart, and many others. Developers can use it to create more than a few dynamic net solutions such as shopping carts, Web calendars, content material management systems, and so on.


PHP is known for its ability to optimize memory. As a result, it never allows server overloading. Instead, it helps in improving a server's processing speed significantly.
While you are the usage of this language for developing web site, you may now not want to apply innumerable codes. The language is capable for minimizing code utilization and comes with its memory development function. Collecting object codes from outside is not commonplace as PHP based web applications are concerned.

However a few clear attributes that make PHP a much sought after language and the reason why most websites are looking to hire PHP developers.

Easy to Manage:  
PHP comes with a normal setting of 1-1 correspondence between files and URLs. This is a great advantage as it helps users (programmers, designers and others) in creating pages and making edits. This feature comes in handy while working on static websites which have a large base of content in it. Making subtle changes to such pages would otherwise require a good deal of over-engineering, but with a PHP framework it becomes easier.

Easy to Scale:  
PHP is easier to scale which makes it all the more transparent to use. Those looking to understand the minutest of details of a code can get a better understanding of it with PHP. Those programming in a much complex framework than PHP would have to make their way through the nitty-gritty’s of various classes and subclasses to actually understand how exactly the code is working. Hence using PHP makes it easier to follow and save time as well.

More Reliable:
What makes PHP a more reliable framework to work on is a separated isolate process within 'Apache'. Hence even if there is some glitch in any one of the processes, the website would still remain virtually unaffected. This is especially helpful for those websites which have a high traffic rate and cannot afford to go down even for a tad while. This is the prime reason why many e-commerce websites implement a PHP framework for web development. 

Runs on All Platforms:
We all look to create a website that would open smoothly on any platform and devices. Especially e-commerce websites need to ensure that they run on all platforms. A PHP web development makes a website run on all leading platforms such as Windows, MAC OS, UNIX and Linux.

Faster TAT:
 Deployment is a mighty easy job with PHP than with other frameworks. Merely copying the files would do. For those who are more efficient can 'sun up' the files or 'rsync' it. Hence, it also saves a good deal of time and reduces the turn-around time (TAT) of business deliverables which makes it a much sought after framework.

Proven Security:
 The ones trying to create a web site with high end security features, it is cautioned to hire a PHP programmer. PHP has numerous layers of security which keeps malicious attacks and threats at bay. That is the cause why e-commerce web sites, wherein e-transactions take place, are all built on a PHP framework. 

Another prominent advantage of using this language is that it can be embedded into HTML without any difficulty. Integrating the language with advanced visual applications such as Ajax and Flash also involves some very simple steps.One feature that, according to experts, plays a big role in making PHP one of the most widely used programming languages is its ability to support several databases including MySQL, Informix, Oracle etc.

These are reasons why people hire PHP programmers to develop a website. It not only adds speed, security and smoothness to a website but also costs less.
