JobTracker dumps TaskTrackers if it takes too long to service an RPC call
-------------------------------------------------------------------------
Key: HADOOP-43
URL: http://issues.apache.org/jira/browse/HADOOP-43
Project: Hadoop
Type: Bug
Components: mapred
Reporter: Bryan Pendleton
If the JobTracker takes too long to service any RPC request, it is unable to
receive emitHeartBeat calls from TaskTrackers. The monitoring thread thus dumps
the TaskTracker, losing any incomplete work and forcing a slow reconnect
process to begin before it starts assigning work again.
