Subject Why we change index state to PENDING_DISABLE on RegionMovedException
Date Tue, 10 Sep 2019 21:29:22 GMT
As I know RegionMovedException is not a problem at all, its just notification that we need
to update meta information about table regions and retry.
Why we do extra work with changing state of index?
