Phil Yang commented on HBASE-18390:
-----------------------------------
I think findbugs warning is unrelated. And whitespace can be fixed while
committing.
bq. ConnectionUtils.addJitter is useless. Can we git rid of it?
Yes, can remove it and its tests while committing.
> Sleep too long when finding region location failed

> If RegionServerCallable#prepare failed when getRegionLocation, the location
> in this callable object is null. And before we retry we will sleep. However,
> when location is null we will sleep at least 10 seconds. And the request will
> be failed directly if operation timeout is less than 10 seconds. I think it
> is no need to keep MIN_WAIT_DEAD_SERVER logic. Use backoff sleeping logic is
> ok for most cases.
