Subject lowering priority on expansive mapreduce job
Date Wed, 26 Oct 2016 17:41:18 GMT
If I'm running a mapreduce job that is very expansive may be because it
scans through every row and every column-qualifier, it is likely going to
keep at least some of the tablet servers very busy and affect other scans
going on.

 

Is there a way to assign such a job a lower priority so it doesn't affect
other scans that might be going on, may it be other mapreduce job or
accumulo scans.

 

How about some accumulo scans that we know are going to be stragglers that
we might want to run at lower priority?

 

Thank you,

Jayesh
