Hi @JAy PaTel go to /var/log/hbase/ and then take a look at master and region log to check if there's an exception. From https://hbase.apache.org/apidocs/org/apache/hadoop/hbase/PleaseHoldException.html you can see: "This exception is thrown by the master when a region server was shut down and restarted so fast that the master still hasn't processed the server shutdown of the first instance, or when master is initializing and client call admin operations, or when an operation is performed on a region server that is still starting."
