> Hadoop: permgen leak due to new statistics thread in Hadoop.
> ------------------------------------------------------------
>
> Key: IGNITE-3203
> URL: https://issues.apache.org/jira/browse/IGNITE-3203
> Project: Ignite
> Issue Type: Task
> Components: hadoop
> Affects Versions: 1.5.0.final, 1.6
> Reporter: Vladimir Ozerov
> Priority: Major
>
> *Problem*
> HADOOP-12829 ticket was implemented recently. It introduces special worker
> thread which monitors file system statistics. When several
> {{HadoopClassLoader}}s are created, one thread start for each of them. As
> this thread is never stopped, classloaders are never unloaded -> leak.
> *Solution*
> We need to investigate on how to hack into this process and prevent start of
> these thread. May be we will have to implement our own threads serving the
> same purpose.
