> Key: HADOOP-9654
> URL: https://issues.apache.org/jira/browse/HADOOP-9654
> Project: Hadoop Common
> Issue Type: Bug
> Components: ipc
> Affects Versions: 2.1.0-beta
> Reporter: Roman Shaposhnik
> Assignee: Ajith S
>
> During my Bigtop testing I made the NN OOM. This, in turn, made all of the
> clients stuck in the IPC call (even the new clients that I run *after* the NN
> went OOM). Here's an example of a jstack output on the client that was
> running:
> {noformat}
> $ hadoop fs -lsr /
> {noformat}
> Stacktrace:
> {noformat}
> /usr/java/jdk1.6.0_21/bin/jstack 19078
