>             Project: Ignite
>          Issue Type: Bug
>          Components: hadoop
>    Affects Versions: sprint-1
>            Reporter: Ivan Veselovsky
>            Assignee: Vladimir Ozerov
>             Fix For: sprint-3

> 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.)
