Jian He commented on YARN-3671:
-------------------------------
Thanks Subru for updating !
- Here, the scheduler is passed in via reference. If the RM switches to standby
and then switches back to active, the scheduler object will be re-created and
the reference will be updated in RMContext, but the reference here won't be
updated, which cause the scheduler object here outdated?
{code}
public FederationStateStoreHeartbeat(FederationStateStore stateStoreClient,
ResourceScheduler scheduler, SubClusterId clusterId) {
this.stateStoreService = stateStoreClient;
this.subClusterId = clusterId;
this.rs = scheduler;
{code}
- "state-store.heartbeat-interval": how about
"state-store.heartbeat-interval-secs"
