Ivan Veselovsky updated IGNITE-494:
-----------------------------------
Attachment: PermGen.png
classes.png
JConsole view of the crash.
Uniform "saw-like" PermGen curve corresponds to the igfs:// backed by hdfs://
client mode.
And fast growing PermGen curve corresponds to the pure hdfs:// client mode.
Abrupt drop of the curve corresponds to the OOM crash.
(PermGen maximum size is 256M, default. Xmx = 1g, default)
> Ignite node runs OutOfMemory when running Hadoop tasks with native Hadoop
> filesystem

> 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: Ivan Veselovsky
> Fix For: sprint-2

> Attachments: 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.
