> HTTP_PORT=""  is seen in job history file after JT recovery in case of lost TT. The .recover file of TestJobTrackerRestartWithLostTracker has empty string as HTTP_PORT. If another time JT is restarted and then JT tries to read the history line and tries to createTaskAttempt, it would get NumberFormatException because of Integer.parseInt(httpPort). We somehow need to log a legal value as HTTP_PORT in the history file OR the exception needs to be caught and proper action is to be taken.
