[jira] Commented: (HADOOP-2924) HOD is trying to bring up task tracker on port which is already in close_wait state

------------------------------------------

This could also happen if the host is using a port as the source port for a connection.

> 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.
