JobTracker should synchronously resolve the tasktracker's network location when
the tracker registers
-----------------------------------------------------------------------------------------------------
Key: HADOOP-3780
URL: https://issues.apache.org/jira/browse/HADOOP-3780
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Amar Kamat
This issue is inspired by HADOOP-3620. In JobTracker, the network address of
tracker gets resolved asynchronously. Now it can be done inline i.e while the
trackers register. This is of great help for HADOOP-3245 where this enhancement
makes the design simpler.
