MiniMRCluster should point TaskTracker's http URL to the loopback address.
--------------------------------------------------------------------------
Key: HADOOP-5871
URL: https://issues.apache.org/jira/browse/HADOOP-5871
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Vinod K V
It currently sets mapred.task.tracker.http.address to 0.0.0.0:0 and so every TT
startup in MiniMRCluster makes a trip to DNS. Changing it to 127.0.0.1:0
decreases 5 seconds for every TT start-up on my local box.
