Subject [jira] [Commented] (MAPREDUCE-4135) MRAppMaster throws IllegalStateException while shutting down
Date Wed, 25 Apr 2012 17:28:18 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4135?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13261823#comment-13261823

Ravi Prakash commented on MAPREDUCE-4135:

I'm sorry I was wrong about my earlier statement:
bq. This is causing the subsequent statement (FileSystem.closeAll() ) to be skipped. So to
fix this JIRA, I'll see what I can do to fix the InterruptedException.
The InterruptedException is thrown and then caught. So its not that. Its MAPREDUCE-4157. The
SIGTERM is sent without any delay on ContainerLaunch.java:337.
