> Fix performance issue of permission check in verifyAndCreateRemoteLogDir
> ------------------------------------------------------------------------
>
> Key: YARN-11578
> URL: https://issues.apache.org/jira/browse/YARN-11578
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Tamas Domok
> Assignee: Tamas Domok
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> YARN-10901 introduced a check to avoid a warn message in NN logs in certain
> situations (when /tmp/logs is not owned by the yarn user), but it adds 3
> NameNode calls (create, setpermission, delete) during log aggregation
> collection, for *every* NM. Meaning, when a YARN job completes, at the YARN
> log aggregation phase this check is done for every job, from every
> NodeManager.
> In 30 minutes 4.2 % of all the NameNode calls were due to this in a cluster.
> "write" calls need a Namesystem writeLock as well, so the impact is bigger.
