Artem Ervits updated HBASE-18735:
---------------------------------
Status: Patch Available (was: Open)
I provided two tests to demonstrate performance of both calls
forceShutdownMiniHBaseCluster() and shutdownMiniHBaseCluster(). I tested with
100 tables and 1000 rows each, on average, new method is 40-50secs faster. I'm
open to suggestions [~jamestaylor].
I also need to fix some checkstyle warnings but seems hbase-server module has
tons of them so this patch is only to demonstrate functionality, I'll follow up
with checkstyle fixes after all reviews are in.
> 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.
