> While bringing up task tracker using random ports, HOD is not checking
> whether the port is in CLOSE_WAIT state. So when it starts task tracker, we
> will be getting an address bind error on that port. We can avoid this error
> if we check for CLOSE_WAIT state on that port before starting the tasktracker.
