Detailed explanation-1: -HBase contains a shell using which you can communicate with HBase. HBase uses the Hadoop File System to store its data. It will have a master server and region servers. The data storage will be in the form of regions (tables).
Detailed explanation-2: -To read data from an HBase table, use the get() method of the HTable class.
Detailed explanation-3: -Start the cluster by running the start-hbase.sh command on node-1. ZooKeeper starts first, followed by the Master, then the RegionServers, and finally the backup Masters. Run the jps command on each node to verify that the correct processes are running on each server.
