[jira] [Created] (HBASE-7248) Improve the resources usage in assignement

nkeywal created HBASE-7248:
------------------------------

             Summary: Improve the resources usage in assignement
                 Key: HBASE-7248
                 URL: https://issues.apache.org/jira/browse/HBASE-7248
             Project: HBase
          Issue Type: Improvement
          Components: master, Region Assignment, regionserver
    Affects Versions: 0.96.0
            Reporter: nkeywal
            Priority: Critical


On top on HBASE-7246 and HBASE-7247, I've changed some parameters:

hbase.regionserver.executor.openregion.threads from 3 to 300
hbase.assignment.zkevent.workers from 5 to 30
hbase.assignment.threads.max from 30 to 300

It makes the assignment time going from 70s to 8s.

Seems there is something to dig here as well...
