[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.
