stack commented on HBASE-21863:
-------------------------------
bq. Judging by the description of YouAreDeadException it was sortof intended
for a different purpose; it was to tell RS that it's already dead from lease
expiration, but doesn't know it due to timing issues on network I guess. Then
it was repurposed for killing RS for incorrect state.
So I made a separate exception cause these are separate concerns, I can inherit
either way.
That is right.
I was thinking that the RegionServer killers could have a common ancestor so
you could avoid if this or that exception, kill.
Thanks for improving the comment (makes sense when you explain it).
So, if we have an existing check, use that instead of add new?
Thanks.
