Task diagnostic info would get missed sometimes.
------------------------------------------------
Key: MAPREDUCE-1563
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1563
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Reporter: Amareshwari Sriramadasu
Fix For: 0.22.0
TaskStatus's diagnostic info is reset in
TaskTracker.cloneAndResetRunningTaskStatuses() method while constructing
TaskTrackerStatus to send the heartbeat. It is also reset after receiving the
response in TaskTracker.transmitHeartbeat() method.
If any task sets diagnostic info between both the clearStatus() calls, the info
is lost.
