Subject [jira] [Updated] (HBASE-18362) hbck should not report split replica parent region from meta as errors
Date Mon, 24 Jul 2017 22:31:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-18362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

huaxiang sun updated HBASE-18362:
---------------------------------
    Description: 
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.
