If you use the HBase Thrift server, complete the following steps. Otherwise, continue with the next step in the upgrade process.

The HBase Thrift server does not support rolling upgrade; you cannot keep it running while you downgrade. To downgrade the Thrift server, stop and start the process.

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

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

To verify that the Thrift server accepts traffic, use a simple Thrift client to connect to the server.

Continue with the next downgrade step.
