Subject setting maximum mapper concurrently running
Date Tue, 27 May 2014 00:52:20 GMT
is there any setting that can set on run time of job for maximum mapper
concurrently running ?

i know there is a jobtracker level parameter that can be set, but that will
be global parameter for every job.  Is it possible to set per job ?
