What is Cloudera CDH?
The company Cloudera gives services to people related to software based on Hadoop system along with support and training to its clients and it is located in the United States.
It also provides CHD (Cloudera Distribution Included Apache Hadoop) and its prime aim is the provision of enterprise level technology. The half of money they get after selling their products is invested in other projects which are open source as well in order to keep increasing the growth of Hadoop platform and probably this makes Cloudera the sponsor for Apache Software Foundation.
To think of which is most clearly the top notch feature of CDH the process of easy installation comes into the user’s mind. It makes really simple and straightforward for users to get all of their projects installed and running on their system in the shortest period of time. Besides the ease of installation, all of the projects have been tested several times and made sure that they work together efficiently.
By testing out the recent addition to CDH versions the CDH3 we can tell that it had all of the important and essential patches which are the prerequisite for durability and cluster security plus it also contains patches HBase deployment which is production ready.
You can run the Hadoop software without any problems using the PowerEdge servers because the base is strong due to their operating system and Java Virtual Machine.
There are actually two frameworks, one of them is Data Storage Framework which is a file system on which the Hadoop uses to keep all of the data on the cluster nodes and the HDFS (Hadoop Distributed File System) is also a portable, scalable and distributed file system.
The other one is Data Processing Framework which is comprised of huge parallel computer framework and the motivation behind this are MapReduce papers of Google.
The network layer is named the next layer of our system’s stack which is a special devoted cluster network, tested and qualified parts have been used to carry out from a design, and this implementation will give the user a top notch performance capability without troubles from external application software.
Moving on to next framework which is namely, Orchestration, Data Access Framework and the last one Client Access Tools, all of these frameworks comprise the Hadoop ecosystem and the Cloudera Distribution Including Apache Hadoop distribution.
The Cloudera Distribution Including Hadoop from the very start was a decent and very clean way to operate the Hadoop. We do not think that CDH is any kind of machine for propaganda which is available in the market.
There have been instances when someone has come to us saying that Hadoop (0.20.2) was at fault for something and we should switch to CDH because “what was what everyone runs and this bug is fixed in cdh” when pressed further a network card or a buggy piece of user code was the actual issue. We do not operate CDH in particular hive because we are a rather advanced user. We want features when we want them (we do not want to wait) and we do our own QA and “release engineering” about when we should upgrade hive.

In general running CDH is a good option, and if you do not have a good reason not to use it you are better off with it, because in particular Cloudera does a good job of backporting features and doing upgrades in a sane way, whereas code Hadoop is a shotgun of versions with a very unclear migration path between them, even worse some releases that were dead on arrival, or even worse some that got backed out of.
