Wangda Tan created YARN-2807:
--------------------------------
Summary: Option "--forceactive" not works as described in usage of
"yarn rmadmin -transitionToActive"
Key: YARN-2807
URL: https://issues.apache.org/jira/browse/YARN-2807
Project: Hadoop YARN
Issue Type: Sub-task
Components: resourcemanager
Reporter: Wangda Tan
Currently the help message of "yarn rmadmin -transitionToActive" is:
{code}
transitionToActive: incorrect number of arguments
Usage: HAAdmin [-transitionToActive <serviceId> [--forceactive]]
{code}
But the --forceactive not works as expected. When transition RM state with
--forceactive:
{code}
yarn rmadmin -transitionToActive rm2 --forceactive
Automatic failover is enabled for
org.apache.hadoop.yarn.client.RMHAServiceTarget@64c9f31e
Refusing to manually manage HA state, since it may cause
a split-brain scenario or other incorrect state.
If you are very sure you know what you are doing, please
specify the forcemanual flag.
{code}
As shown above, we still cannot transitionToActive when automatic failover is
enabled with --forceactive.
The option can work is: {{--forcemanual}}, there's no place in usage describes
this option. I think we should fix this
