Michael Stack created HBASE-24247:
-------------------------------------
Summary: Failed multi-merge because two regions not adjacent
(legitimately).
Key: HBASE-24247
URL: https://issues.apache.org/jira/browse/HBASE-24247
Project: HBase
Issue Type: Bug
Reporter: Michael Stack
Below is a multi-merge created by FixMeta provoked by 'hbck2 fixMeta'. The
merge is legitimate in that indeed all Regions overlap. The merge is cutoff off
at the current max of 10 Regions-at-a-time (which is another issue). The merge
fails though because two Regions in the Set of Regions to merge are not
adjacent when we do our pre-flight check. We could 'force' the merge but better
if the 'check' is improved.
