Junhong Xu commented on HBASE-22699:
------------------------------------

[~stack] just clean the region meta cache. And would it be  better to keep the 
meta cache  when the exception is RegionOpeningException and just sleep or fail 
fast because we are sure about the region is on the right server, just a moment 
will be OK ? BTW that's why the former UT failed. 

> refactor isMetaClearingException
