Ashish Singhi created HBASE-13098:
-------------------------------------

             Summary: HBase Connection Control
                 Key: HBASE-13098
                 URL: https://issues.apache.org/jira/browse/HBASE-13098
             Project: HBase
          Issue Type: New Feature
          Components: security
    Affects Versions: 0.98.10
            Reporter: Ashish Singhi
            Assignee: Ashish Singhi


It is desirable to set the limit on the number of client connections permitted to the HBase
server by controlling with certain system variables/parameters. Too many connections to the
HBase server imply too many queries and MR jobs running on HBase. This can slow down the performance
of the system and lead to denial of service. Hence such connections need to be controlled.
Using too many connections may just cause thrashing rather than get more useful work done.
This is kind off inspired from http://www.ebaytechblog.com/2014/08/21/quality-of-service-in-hadoop/#.VO2JXXyUe9y
