----------------------------------
> Ignite node runs OutOfMemory when running Hadoop tasks with native Hadoop

> Key: IGNITE-494
> URL: https://issues.apache.org/jira/browse/IGNITE-494
> Project: Ignite
> Issue Type: Bug
> Components: hadoop
> Affects Versions: sprint-1
> Reporter: Ivan Veselovsky
> Assignee: Vladimir Ozerov
> Fix For: sprint-3
>
> Attachments: IGNITE-494--b.patch, IGNITE-494--c.patch,
> IGNITE-494--d.patch, PermGen.png, classes.png
>
>
> To reproduce: tun terasort Hadoop sample using Ignite mapred engine with
> native Hadoop filesystem (original Hadoop core-site.xml, with e.g.
> fs.defaultFs=hdfs://quickstart.cloudera:8020).
> After ~10 runs of the teragen sample without Ignite node restart the node
> crashes with "Caused by: java.lang.OutOfMemoryError: PermGen space"
> Important to note that this does *not* happen if igfs:// filesystem backed by
> hdfs:// is used: in this case PermGen is cleared okay.
> The below screenshots illustrate the problem.
> (Heap dumps are also available, but they are too large to be attached.)
