Simple script for managing HBase processes
When the nodes in the cluster keep growing, you might want to find tools to show and manage the HBase-related processes running in the cluster. As the hadoop user is configured to be able to SSH from the master node to each slave node in the cluster without a password, it is easy for us to write a simple script to achieve this task with SSH login for every node and show/manage the running HBase processes on that node.
As Hadoop/HBase processes run in a Java Virtual Machine (JVM) , our task is to manage these Java processes in the cluster.
In this recipe, we will create a simple script to show all the running Java processes owned by the hadoop user in an HBase cluster.
