----------------------------------
Summary: NPE while decommissioning an OM node
Key: HDDS-7707
URL: https://issues.apache.org/jira/browse/HDDS-7707
Project: Apache Ozone
Issue Type: Bug
Components: OM HA
Affects Versions: 1.3.0
Reporter: Kirill Sizov
OM decommission command looks as follows:
{noformat}
ozone admin om decommission -id=<om-service-id>
-nodeid=<decommissioning-om-node-id>
-hostname=<decommissioning-om-node-address> [optional --force]
{noformat}
If nodeid does not exist (likely just a misprint), the command fails with an
NPE:
{noformat}
java.lang.NullPointerException
