7.2. Downgrade HBase REST Server

If you use the HBase REST server, follow these steps. Otherwise, continue with the next step in the upgrade process.

The HBase REST server does not support rolling downgrade; you can’t keep it running as you downgrade. To downgrade the REST server, stop and start the process:

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

su - hbase -c "/usr/hdp/current/hbase-master/bin/hbase-daemon.sh start rest --infoport <port>"

(for example, port 8085)

When finished, verify that the REST server accepts traffic. 17000 is the default port for REST:


Continue with the next downgrade step.
