Suresh Srinivas commented on HDFS-4940:
---------------------------------------
bq. Have you checked out the heap dump?
yes. I agree with your assessment based on that alone.
bq. I'm still not sure how the test is causing this problem
It would be good to get bigtop results for this to understand what causes this.

> Bigtop's TestCLI when executed against Hadoop 2.1.0 seems to make it OOM
> quite reliably regardless of the heap size settings. I'm attaching a heap
> dump URL. Alliteratively anybody can just take Bigtop's tests, compiled them
> against Hadoop 2.1.0 bits and try to reproduce it.
