Subject [jira] [Commented] (ACCUMULO-507) Large amount of ranges can prevent job from kicking off
Date Fri, 19 Apr 2013 19:41:16 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13636780#comment-13636780
] 

Keith Turner commented on ACCUMULO-507:
---------------------------------------

deleteOnExit works if the process is killed w/ SIGTERM.   It will not work if the nodes dies
or the process is killed w/ SIGKILL.  A job submit directory was mentioned,  I was wondering
if the file would be placed there and if it would be periodically cleaned up by the job tracker.
 But the file was placed in user home dir, so that would be left in case of unclean shutdown.
  Could the file be placed somewhere that the jobtracker does cleanup?

> We use the various ranges a user provides to create splits. Those get read when the job
is submitted by the client. On the client side, those ranges are used to get all of the splits,
and then the job is started. If the configuration is too large, the job will fail to submit
(this size is configurable, but that's besides the point). We should look into clearing the
ranges out of the jobconf if it's large to prevent this error, since at this point the ranges
are no longer needed in the configuration.
