> Nodemanager leaking RawLocalFilesystem instances for user "testing"
> -------------------------------------------------------------------
>
> Key: YARN-4570
> URL: https://issues.apache.org/jira/browse/YARN-4570
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.6.0
> Reporter: Jason Lowe
> Assignee: Chang Li
>
> I recently ran across a NodeManager that was running slowly due to excessive
> GC. Digging into the heap I saw that most of the issue was leaked filesystem
> statistics data objects which has been fixed in HADOOP-12107. However I also
> noticed there were many thousands of RawLocalFilesystem objects on the heap,
> far more than any other FileSystem type. Sampling a number of them showed
> that they were for the "testing" user.
