Subject [jira] [Commented] (GIRAPH-637) Expose a mapred.child.java.opts xmx option from GiraphRunner
Date Wed, 17 Apr 2013 09:03:16 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-637?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13633912#comment-13633912

Kevin Savage commented on GIRAPH-637:
-------------------------------------

We were seeing GiraphRunner complain because -Dmapred.child.java.opts was not an option it
was expecting. It looked like this was happening in the apache cli stuff.
