stack commented on HBASE-18735:
-------------------------------
RS's in MiniHBaseCluster already have a pseudo-kill call. At end of test,
spinning through all alive regions doing a kill should get you what you want.
Would be interested in timings to see how much difference this makes.
> Provide a fast mechanism for shutting down mini cluster

> 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.
