Issue: Start-hbase startup Hmaster Not start, view log the above error occurred. Operation category Read is a supported in the state standby this line of code can be seen, read does not support backup status. Check that the host Namenode my master is in a backup state.

Workaround: Start the namenode of the host on which the configured Hmaster resides, hadoop-daemon.sh start Namenode, and leave it in the active state, at which point the start-hbase is started. The problem that has plagued the day has finally been solved.

Second, check the disk footprint, df-h if the root directory occupies a full space, this can also cause this situation. This will clean up the files under the root directory.

Workaround: Modify the Hosts file under local Windows to add the IP of each node of the cluster and the corresponding hostname.
