Subject [jira] [Created] (HBASE-11319) No need for favored node mapping initialization to scan meta
Date Tue, 10 Jun 2014 16:13:02 GMT
Jimmy Xiang created HBASE-11319:
-----------------------------------

             Summary: No need for favored node mapping initialization to scan meta
                 Key: HBASE-11319
                 URL: https://issues.apache.org/jira/browse/HBASE-11319
             Project: HBase
          Issue Type: Improvement
            Reporter: Jimmy Xiang
            Assignee: Jimmy Xiang
            Priority: Minor


During a clean re/start, favored node mapping initialization scans meta for an assignment
snapshot. We can avoid this scan since such info is already loaded into region states. For
small cluster, this is not a big deal. However, if there are lots of regions, the scan is
better not to do.
