Hi ,
I am using hadoop 0.20.2 . I have configured for fair scheduler in hadoop .
Now when i fire two queries simultaneously , each running map reduce ,
second query waits for map/reduce task slots until first query release some
. many a times queries are over big data ~ 500 GB , so second query has to
wait for a long time to get its turn . Is there any way to control maximum
number of map/reduce slots to be used by a specific job ?
Thanks and Regards
