Subject [jira] Created: (HADOOP-43) JobTracker dumps TaskTrackers if it takes too long to service an RPC call

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.
