Sergey Shelukhin commented on HBASE-7948:
-----------------------------------------
Can you please elaborate about more dangerous parts?
In my experience it's not safe to trust anything forever as a general
principle, not because I think RS code is unreliable.
Even hardware itself is not reliable. Something as simple can happen as
coincidence of RS bug and watchdog bug. Maybe RS will go into some crazy state
where noone can reach it except client. Perhaps someone was debugging and
killed some threads or whatever, so now RS won't die and behaves abnormally.
If master/RS cannot trust itself it may assert/halt/shut down, to prevent data
loss.
But for client there's no data loss potential from flushing the cache, but
there's potential to be stuck forever in case of abnormal RS behavior. With
remote things I prefer to be defensive on all sides if practical :)
