Description

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.
