> LevelDBCacheTimelineStore in ATS 1.5 leaks native memory
> --------------------------------------------------------
>
> Key: YARN-9040
> URL: https://issues.apache.org/jira/browse/YARN-9040
> Project: Hadoop YARN
> Issue Type: Bug
> Components: timelineserver
> Affects Versions: 2.8.0
> Reporter: Tarun Parimi
> Assignee: Tarun Parimi
> Priority: Major
> Attachments: YARN-9040.001.patch
>
>
> When LevelDBCacheTimelineStore from YARN-4219 is used as ATS 1.5 entity caching storage, we observe memory leak due to leveldb files even after the fix of YARN-5368 .
> Top output shows 0.024TB (25GB) RES, even though heap size is only 8GB.
>
>
> {code:java}
> PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
> 25519 yarn 20 0 33.024g 0.024t 41468 S 6.2 26.0 21:07.39 /usr/java/default/bin/java -Dproc_timelineserver -Xmx8192m
> {code}
>
> Lsof shows a lot of open timeline-cache.ldb files which are referenced by ATS, even though are deleted (DEL), since they are not present when listing them .

> Looks like LevelDBCacheTimelineStore is not closing these files as the LevelDB DBIterator is not closed.
