Sandeep Guggilam commented on HBASE-24069:
------------------------------------------
[~apurtell] I started looking at this , need few clarifications with respect to
the use cases we are trying to solve
# Retry with exponentialBackOff for region close requests
Is this primarily meant to deal with the case where the RS might be busy in
responding to the close request temporarily because of incoming load but might
get free in some time where the retry without exponentialBackOff would quickly
fail it to FAILED_CLOSE state ? Is there any other case which would help with
the fix ?
2. Retry with exponentialBackOff for split requests
Can you please help me understand the case where the SPLIT request would
ultimately end up in FAILED_CLOSE state ?
> Extend HBASE-16209 strategy (Provide an ExponentialBackOffPolicy sleep
> between failed region open requests) to region close and split requests

> In HBASE-16209 we provide an ExponentialBackOffPolicy sleep between failed
> region open requests. This should be extended to also apply to region close
> and split requests. Will reduce the likelihood of FAILED_CLOSE transitions in
> production by being more tolerant of temporary regionserver loading issues,
> e.g. CallQueueTooBigException.
