Tarun Parimi commented on YARN-8279:
------------------------------------
This issue occurs since LogAggregationIndexedFileController appends "-ifile" to
the suffix configured in yarn.nodemanager.remote-app-log-dir-suffix*_,_* when
yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix is not configured
as seen in below code.
{code:java}
if (this.remoteRootLogDirSuffix == null
|| this.remoteRootLogDirSuffix.isEmpty()) {
this.remoteRootLogDirSuffix = conf.get(
YarnConfiguration.NM_REMOTE_APP_LOG_DIR_SUFFIX,
YarnConfiguration.DEFAULT_NM_REMOTE_APP_LOG_DIR_SUFFIX)
+ "-ifile";
}
{code}
Not sure why "-ifile" is being appended here by default. To ensure that it
doesn't aggregates logs in the same folder the older
LogAggregationTFileController logs were present?

> Key: YARN-8279
> URL: https://issues.apache.org/jira/browse/YARN-8279
> Project: Hadoop YARN
> Issue Type: Bug
> Components: log-aggregation
> Affects Versions: 2.7.3
> Reporter: Prabhu Joseph
> Assignee: Tarun Parimi
> Priority: Major
>
> AggregationLogDeletionService does not honor
> yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix.
> AggregationLogService writes the logs into /app-logs/<user-dir>/logs-ifile
> where as AggregationLogDeletion tries to delete from
> /app-logs/<user-dir>/logs.
> Workaround is to set
> yarn.log-aggregation.IndexedFormat.remote-app-log-dir-suffix and
> yarn.nodemanager.remote-app-log-dir-suffix to same value "logs-ifile"
> AggregationLogDeletionService has to check the format and based upon that
> choose the suffix. Currently it only checks the older suffix
> yarn.nodemanager.remote-app-log-dir-suffix.
> AggregatedLogDeletionService tries to delete older suffix directory.
