Todd Lipcon commented on HBASE-4275:
------------------------------------
Adding a new RPC shouldn't be wire-incompatible -- worst that happens is the RS
gets an exception when trying to report its fatal error. But at that point it's
shutting down anyway, and we aren't any worse off than before :)
> RS should communicate fatal "aborts" back to the master
> -------------------------------------------------------

> Key: HBASE-4275
> URL: https://issues.apache.org/jira/browse/HBASE-4275
> Project: HBase
> Issue Type: Improvement
> Components: master, regionserver
> Affects Versions: 0.92.0
> Reporter: Todd Lipcon
>
> When a region server aborts, it should attempt to send an RPC to the master
> that contains (a) the reason for aborting, and (b) the last several KB of log
> messages, if available. This should help a lot in debugging.
