             Summary: YARN: Unsupported "transitionToObserver" option displaying for rmadmin
                 Key: YARN-9985
                 URL: https://issues.apache.org/jira/browse/YARN-9985
             Project: Hadoop YARN
          Issue Type: Bug
          Components: RM, yarn
    Affects Versions: 3.2.1
            Reporter: Souryakanta Dwivedy

Unsupported "transitionToObserver" option displaying for rmadmin command

Check the options for Yarn rmadmin command
It will display the "-transitionToObserver <serviceId>" option which is not supported

 by yarn rmadmin command which is wrong behavior.
 But if you check the yarn rmadmin -help it will not display any option  "-transitionToObserver





install/hadoop/resourcemanager/bin> ./yarn rmadmin -help
rmadmin is the command to execute YARN administrative commands.
The full syntax is:

yarn rmadmin [-refreshQueues] [-refreshNodes [-g|graceful [timeout in seconds] -client|server]]
[-refreshNodesResources] [-refreshSuperUserGroupsConfiguration] [-refreshUserToGroupsMappings]
[-refreshAdminAcls] [-refreshServiceAcl] [-getGroup [username]] [-addToClusterNodeLabels <"label1(exclusive=true),label2(exclusive=false),label3">]
[-removeFromClusterNodeLabels <label1,label2,label3>] [-replaceLabelsOnNode <"node1[:port]=label1,label2
node2[:port]=label1"> [-failOnUnknownNodes]] [-directlyAccessNodeLabelStore] [-refreshClusterMaxPriority]
[-updateNodeResource [NodeID] [MemSize] [vCores] ([OvercommitTimeout]) or -updateNodeResource
[NodeID] [ResourceTypes] ([OvercommitTimeout])] *{color:#FF0000}[-transitionToActive [--forceactive]
<serviceId>]{color} {color:#FF0000}[-transitionToStandby <serviceId>]{color}*
[-getServiceState <serviceId>] [-getAllServiceState] [-checkHealth <serviceId>]
[-help [cmd]]

-refreshQueues: Reload the queues' acls, states and scheduler specific properties.
 ResourceManager will reload the mapred-queues configuration file.
 -refreshNodes [-g|graceful [timeout in seconds] -client|server]: Refresh the hosts information
at the ResourceManager. Here [-g|graceful [timeout in seconds] -client|server] is optional,
if we specify the timeout then ResourceManager will wait for timeout before marking the NodeManager
as decommissioned. The -client|server indicates if the timeout tracking should be handled
by the client or the ResourceManager. The client-side tracking is blocking, while the server-side
tracking is not. Omitting the timeout, or a timeout of -1, indicates an infinite timeout.
Known Issue: the server-side tracking will immediately decommission if an RM HA failover occurs.
 -refreshNodesResources: Refresh resources of NodeManagers at the ResourceManager.
 -refreshSuperUserGroupsConfiguration: Refresh superuser proxy groups mappings
 -refreshUserToGroupsMappings: Refresh user-to-groups mappings
 -refreshAdminAcls: Refresh acls for administration of ResourceManager
 -refreshServiceAcl: Reload the service-level authorization policy file.
 ResourceManager will reload the authorization policy file.
 -getGroups [username]: Get the groups which given user belongs to.
 -addToClusterNodeLabels <"label1(exclusive=true),label2(exclusive=false),label3">:
add to cluster node labels. Default exclusivity is true
 -removeFromClusterNodeLabels <label1,label2,label3> (label splitted by ","): remove
from cluster node labels
 -replaceLabelsOnNode <"node1[:port]=label1,label2 node2[:port]=label1,label2"> [-failOnUnknownNodes]
: replace labels on nodes (please note that we do not support specifying multiple labels on
a single host for now.)
 [-failOnUnknownNodes] is optional, when we set this option, it will fail if specified nodes
are unknown.
 -directlyAccessNodeLabelStore: This is DEPRECATED, will be removed in future releases. Directly
access node label store, with this option, all node label related operations will not connect
RM. Instead, they will access/modify stored node labels directly. By default, it is false
(access via RM). AND PLEASE NOTE: if you configured yarn.node-labels.fs-store.root-dir to
a local directory (instead of NFS or HDFS), this option will only work when the command run
on the machine where RM is running.
 -refreshClusterMaxPriority: Refresh cluster max priority
 -updateNodeResource [NodeID] [MemSize] [vCores] ([OvercommitTimeout])
 [NodeID] [resourcetypes] ([OvercommitTimeout]). : Update resource on specific node.
 -transitionToActive [--forceactive] <serviceId>: Transitions the service into Active
 -transitionToStandby <serviceId>: Transitions the service into Standby state
 -getServiceState <serviceId>: Returns the state of the service
 -getAllServiceState: Returns the state of all the services
 -checkHealth <serviceId>: Requests that the service perform a health check.
The HAAdmin tool will exit with a non-zero exit code
if the check fails.
 -help [cmd]: Displays help for the given command or all commands if none is specified.
