             Summary: Tools/API to read favored nodes for region(s)
                 Key: HBASE-17684
                 URL: https://issues.apache.org/jira/browse/HBASE-17684
             Project: HBase
          Issue Type: Sub-task
          Components: FavoredNodes
            Reporter: Thiruvel Thirumoolan
            Assignee: Thiruvel Thirumoolan


We need APIs to read FN from Master. This will help in troubleshooting when regions are in RIT due to all FN being dead etc. For small clusters, we could just read from SnapshotOfRegionAssignmentFromMeta, but for large clusters it takes 4-5 mins.
