      Description

      The tasktracker expiry interval is hardcoded to 10 mins with the MRConstants.TASKTRACKER_EXPIRY_INTERVAL constant.

      For small clusters, running small jobs, this interval is too high.

      Making it configurable it would require:

      • Introducing a 'tasktracker.expiry.interval' property with default value of 10 mins.
      • Load the property in the JobTracker
      • Change the 5 usages of the constant by a property in the JobTracker
      • Remove the constant from MRConstants
      • add default value to the hadoop-default.xml file
