------------------------------------

             Summary: Provide a fast mechanism for shutting down mini cluster
                 Key: HBASE-18735
                 URL: https://issues.apache.org/jira/browse/HBASE-18735
             Project: HBase
          Issue Type: Wish
            Reporter: Samarth Jain


The current mechanism of shutting down a mini cluster through HBaseTestingUtility.shutDownMiniCluster
can take a lot of time when the mini cluster almost has a lot of tables. A lot of this time
is spent in closing all the user regions. It would be nice to have a mechanism where this
shutdown can happen quickly without having to worry about closing these user regions. At the
same time, this mechanism would need to make sure that all the critical system resources like
file handles and network ports are still released so that subsequently initialized mini clusters
on the same JVM or system won't run into resource issues. This would make testing using HBase
mini clusters much faster and immensely help out test frameworks of dependent projects like
Phoenix.
