Sergey Shelukhin updated HBASE-10175:
-------------------------------------

    Attachment: HBASE-10175.patch

The first option; simple patch.

ChaosMonkey is now so abstract that I wouldn't venture to spend the time needed to make the
actions talk to each other... ;)

> ChaosMonkey with one destructive and one volatility (flush-compact-split-etc.) threads
steps on its own toes and logs a lot of exceptions.
> A simple solution would be to catch most (or all), like NotServingRegionException, and
log less (not a full callstack for example, it's not very useful anyway).
> A more complicated/complementary one would be to keep track which regions the destructive
thread affects and use other regions for volatile one.
