------------------------------------
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.
