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 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
