> As described in HBASE-18247, replica region shows up as key in meta table. We need to
find out the code/logic introducing the issue. I suspected that it was introduced by hbck,
but last round of code review did not find anything. Create jira to track this effort.
> Before Catalog Janitor cleans up the split parent region from meta, hbck is reporting
split replica parent regions as errors and if -fixSplitParents is used, the replica parent
region will show up as key in meta table. It needs to be avoided.
