Subject [jira] Created: (HADOOP-4651) JobTracker.addNewTracker() unnecessarily resolves already resolved nodes
Date Thu, 13 Nov 2008 08:12:46 GMT
JobTracker.addNewTracker() unnecessarily resolves already resolved nodes
------------------------------------------------------------------------

                 Key: HADOOP-4651
                 URL: https://issues.apache.org/jira/browse/HADOOP-4651
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Amar Kamat


_hostnameToNodeMap_ maintains a map from _hostname_ to _resolved-address_. {{JobTracker.addNewTracker()}}
resolves a node's address if the node is not present in _hostnameToNodeMap_ but uses _tracker-name_
to index into _hostnameToNodeMap_ instead of _hostname_.
