3.6. Upgrade HBase Master(s)

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

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.
