Michael Stack commented on HBASE-24585:
---------------------------------------
Thanks for input [~zhangduo] Yeah, the main Handler system has lots of traps in
place to cut off exception throws. Need some here too.
> If RSProcedureHandler throws exception, it aborts the hosting RS

> Project: HBase
> Issue Type: Bug
> Reporter: Michael Stack
> Priority: Major
>
> HBASE-24574 proc v2 distributed log splitting is enabled. A remote split
> fails because it was interrupted. The InterruptedException became an IOE and
> then bubbled up and out of the RSPH below causing a RS abort.

> The remote-procedure framework needs to be more resilient? Log the exception
