Subject [jira] [Updated] (HBASE-20001) cleanIfNoMetaEntry() uses encoded instead of region name to lookup region
Date Thu, 15 Feb 2018 04:07:00 GMT

     [ https://issues.apache.org/jira/browse/HBASE-20001?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Francis Liu updated HBASE-20001:
--------------------------------
    Description: 
In RegionStates.cleanIfNoMetaEntry()

{{if (MetaTableAccessor.getRegion(server.getConnection(), hri.getEncodedNameAsBytes()) ==
null) {}}

{{regionOffline(hri);}}

{{FSUtils.deleteRegionDir(server.getConfiguration(), hri);}}
}

But api expects regionname

{{public static Pair<HRegionInfo, ServerName> getRegion(Connection connection, byte
[] regionName)}}

So we might end up cleaning good regions.
