Subject [jira] [Commented] (YARN-9425) Make initialDelay configurable for FederationStateStoreService#scheduledExecutorService
Date Sat, 01 Jun 2019 00:28:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16853502#comment-16853502
] 

Giovanni Matteo Fumarola commented on YARN-9425:
------------------------------------------------

Thanks [~shenyinjie] for working on this.
NIT: Looks like the patch has a different coding style from the class.
1) It should be "public static final String FEDERATION_STATESTORE_HEARTBEAT_INITIAL_DELAY_SECS
="
2) YarnConfiguration.FEDERATION_STATESTORE_HEARTBEAT_INITIAL_DELAY_SECS should go in the
same line.
3) The description in yarn-default should be "Initial delay for federation state-store heartbeat
service"

> When enable YARN federation, subclusters info in Router Web UI  cannot be loaded immediately,
and client cannot find any active subclusters after 5mins by default ,which is configured
by "yarn.federation.state-store.heartbeat-interval-secs".
> IMA,we should seperate 'initialDely' and 'delay' for FederationStateStoreService#scheduledExecutorService.
