> 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
