> 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.
