Subject [jira] [Commented] (HBASE-18796) Admin#isTableAvailable returns incorrect result before daughter regions are opened
Date Tue, 12 Sep 2017 12:34:00 GMT

Abhishek Singh Chouhan commented on HBASE-18796:
------------------------------------------------

Need to check why locations were added during the meta update when the method description
says that it does not add the location (which seems like the correct behavior).

During the time of split server location are added to the meta entries in MetaTableAccessor#splitRegion
although the description of the method says "Does not add the location information to the
daughter regions since they are not open yet.". At this point during the split daughter regions
are not actually open, so we can get to a state where parent is offline, daughters are not
yet open but isTableAvailable returns true.
