> In the thread [Giving a chance to buggy coprocessors to clean up|http://osdir.com/ml/general/2013-12/msg17334.html]
I brought up the issue that coprocessors currently don't have a chance to release their own
resources (be they internal resources within the JVM, or external resources elsewhere) when
they get forcefully removed due to an uncaught exception escaping.
> It would be nice to fix that, either by adding an API called by the {{CoprocessorHost}}
when killing a faulty coprocessor, or by guaranteeing that the coprocessor's {{stop()}} method
will be invoked then.
> This feature request is actually pretty important due to bug HBASE-9046, which means
that it's not possible to properly clean up a coprocessor without restarting the RegionServer
(!!).
