Subject [jira] [Commented] (ACCUMULO-507) Large amount of ranges can prevent job from kicking off
Date Fri, 19 Apr 2013 18:57:16 GMT

Billie Rinaldi commented on ACCUMULO-507:
-----------------------------------------

The workaround does require a restart of the jobtracker, so I will go ahead with the patch;
but since there's a workaround, I'll only check it into trunk.

> 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.
