Subject [jira] Commented: (HADOOP-5885) Error occurred during initialization of VM
Date Wed, 27 May 2009 17:01:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713644#action_12713644
] 

Arun C Murthy commented on HADOOP-5885:
---------------------------------------

This looks like a bad misconfiguration - what is the JVM heapsize (mapred.child.java.opts)?
Can you try bumping it up to *-Xmx512*?

> we are doing a project in hadoop. We are creating hadoop cluster using virtual systems(slaves
both real and virtual machines) using Openvz kernel.
> Since we want to test the setup we required GB of data , So we run RandomWriter job in
our cluster .
>                       But it showed lots of errors. So we stop all our virtual system
and carried the job in the real cluster(slaves involving only real machine). And we got the
the job done(i.e Random Writter job is successfully done).
