Subject [jira] [Commented] (MAPREDUCE-3260) Yarn app stuck in KILL_WAIT state
Date Tue, 25 Oct 2011 16:58:32 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13135232#comment-13135232
] 

Todd Lipcon commented on MAPREDUCE-3260:
----------------------------------------

There seem to be some reducers stuck in KILLING state on some of the nodes. The only non-daemon
thread is:

{code}
"main" prio=10 tid=0x0000000046f7b800 nid=0x3774 waiting on condition [0x000000004033e000]
   java.lang.Thread.State: TIMED_WAITING (sleeping)
        at java.lang.Thread.sleep(Native Method)
        at java.lang.Thread.sleep(Thread.java:298)
        at java.util.concurrent.TimeUnit.sleep(TimeUnit.java:328)
        at org.apache.hadoop.mapred.YarnChild.main(YarnChild.java:117)
{code}

Logs in the NM show the following which looks like a race:
