Subject [jira] [Commented] (HDFS-4940) namenode OOMs under Bigtop's TestCLI
Date Fri, 26 Jul 2013 19:13:49 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13721096#comment-13721096
] 

Colin Patrick McCabe commented on HDFS-4940:
--------------------------------------------

HADOOP-9676 was not the root cause.  It was just a secondary issue that was making debugging
more difficult.  We are still waiting on more data (such as logs) to help understand why BigTop's
TestCLI is failing.

Roman will be back from vacation next week and I believe he said "I'll totally pick this JIRA
back up once I get back."  So I will assign this to him.

> 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.
