> Remove write lock for processCommandFromActor of DataNode to reduce impact on
> heartbeat
> ---------------------------------------------------------------------------------------
>
> Key: HDFS-16898
> URL: https://issues.apache.org/jira/browse/HDFS-16898
> Project: Hadoop HDFS
> Issue Type: Improvement
> Affects Versions: 3.3.4
> Reporter: farmmamba
> Assignee: farmmamba
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> Now in method processCommandFromActor, we have code like below:
>
> {code:java}
> writeLock();
> try {
> if (actor == bpServiceToActive) {
> return processCommandFromActive(cmd, actor);
> } else {
> return processCommandFromStandby(cmd, actor);
> }
> } finally {
> writeUnlock();
> } {code}
> if method processCommandFromActive costs much time, the write lock would not
> release.
>
> It maybe block the updateActorStatesFromHeartbeat method in
> offerService，furthermore, it can cause the lastcontact of datanode very high,
> even dead when lastcontact beyond 600s.
> {code:java}
> bpos.updateActorStatesFromHeartbeat(
> this, resp.getNameNodeHaState());{code}
> here we can make write lock fine-grain in processCommandFromActor method to
> address this problem
>
