[jira] [Commented] (PIG-3517) Fix PermGen error in Pig Unit test on Hadoop 2

["Rohini Palaniswamy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PIG-3517?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13795709#comment-13795709 ] 

Rohini Palaniswamy commented on PIG-3517:
-----------------------------------------

Does ANT_OPTS="-XX:MaxPermSize=xxx" work with forked junit tests? I was running builds using -DdebugArgs="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=128M". 

It is good to have this fixed by default without having to specify manually.  Not sure what the behaviour is when there are two jvmarg lines. http://ant.apache.org/manual/using.html#arg says either of value or line but not both.  If that is the case, can we do <jvmarg line="-XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=128M ${debugArgs}"/> ?

> Hit PermGen error in Pig Unit test when testing Hadoop 2. We can use ANT_OPTS="-XX:MaxPermSize=xxx" to make test work. But it is better to fix it in build.xml.
