Ambari: A web-based tool for provisioning, managing, and monitoring Apache Hadoop clusters, which includes support for Hadoop HDFS, Hadoop MapReduce, Hive, HCatalog, HBase, ZooKeeper, Oozie, Pig, and Sqoop. Understanding the reason for using R and Hadoop together I would also say that sometimes the data resides on the HDFS (in various formats). Since a lot of data analysts are very productive in R, it is natural to use R to compute with the data stored through Hadoop-related tools. As mentioned earlier, the strengths of R lie in its ability to analyze data using a rich library of packages but fall short when it comes to working on very large datasets.
For this, we need several nodes configured with a single node Hadoop cluster. To install Hadoop on multinodes, we need to have that machine configured with a single node Hadoop cluster as described in the last section. After getting the single node Hadoop cluster installed, we need to perform the following steps: In the networking phase, we are going to use two nodes for setting up a full distributed Hadoop mode. Among these two, one of the nodes will be considered as master and the other will be considered as slave.
