The last three steps for core-cluster master processes are for HBase.
Upgrade each HBase Master one by one. Shut down the HBase Master process, switch to the new version, and start the master process:
su - hbase -c "/usr/hdp/current/hbase-master/bin/hbase-daemon.sh stop
master"
hdp-select set hbase-master 2.2.4.2-2
su - hbase -c "/usr/hdp/current/hbase-master/bin/hbase-daemon.sh start
master"
During and after the upgrade process, all running jobs should continue to make progress without restarting.
