[jira] [Commented] (HADOOP-11055) non-daemon pid files are missing

    [ https://issues.apache.org/jira/browse/HADOOP-11055?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14119047#comment-14119047 ] 

Allen Wittenauer commented on HADOOP-11055:
-------------------------------------------

OK, this appears to be fairly easy to solve.  The big thing is that the pid file var needs to get sent to start_daemon so that it can write the pid file *before* launching java.  The exec will replace the running process with the java, but the pid should not change.  

This, however, means breaking/updating the params that get sent to start_daemon. Since this is an unreleased version, not a big deal.
