Subject [jira] [Commented] (HADOOP-8326) test-patch can leak processes in some cases
Date Thu, 31 May 2012 20:03:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8326?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286884#comment-13286884

Robert Joseph Evans commented on HADOOP-8326:
---------------------------------------------

This is still happening and on hadoop3 there are currently 8+ leaked processes.  I don't think
we are seeing the test failures we saw before because all of the mini clusters use ephemeral
ports now.

I would like to check in this change but I am a bit nervous about doing so because I may be
killing off more then I should.  I am killing off everything in the same process group.  So
if I run {code}test-patch.sh ... | less{code} less is getting killed too.  I don't really
know for sure if this will cause problems for Jenkins or not, it depends on how Jenkins is
launching test-patch.

> test-patch.sh can leak processes in some cases.  These leaked processes can cause subsequent
tests to fail because they are holding resources, like ports that the others may need to execute
correctly.
