6.1. Downgrade the HBase RegionServer

  1. Shut down the RegionServer, switch to the previous version, and start the server:

    su - hbase -c "/usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh stop regionserver"

    hdp-select set hbase-regionserver

    su - hbase -c "/usr/hdp/current/hbase-regionserver/bin/hbase-daemon.sh start regionserver"

  2. Verify that the RegionServer joined the HBase cluster as a live server. The results of the following command sequence should list the downgraded RegionServer as a live server process:

    su – hbase

    echo 'status "detailed"' | hbase shell

Continue with the next downgrade step.
