> yarn.nodemanager.remote-app-log-dir structure is not scalable
> -------------------------------------------------------------
>
> Key: YARN-6929
> URL: https://issues.apache.org/jira/browse/YARN-6929
> Project: Hadoop YARN
> Issue Type: Bug
> Components: log-aggregation
> Affects Versions: 2.7.3
> Reporter: Prabhu Joseph
> Assignee: Prabhu Joseph
> Attachments: YARN-6929.1.patch, YARN-6929.patch
>
>
> The current directory structure for yarn.nodemanager.remote-app-log-dir is
> not scalable. Maximum Subdirectory limit by default is 1048576 (HDFS-6102).
> With retention yarn.log-aggregation.retain-seconds of 7days, there are more
> chances LogAggregationService fails to create a new directory with
> FSLimitException$MaxDirectoryItemsExceededException.
> The current structure is
> <yarn.nodemanager.remote-app-log-dir>/<user>/logs/<job_name>. This can be
> improved with adding date as a subdirectory like
> <yarn.nodemanager.remote-app-log-dir>/<user>/logs/<date>/<job_name>
> {code}
