On BDA V4.2/CDH 5.4.0 the impala daemon on one node can not start due to a problem
binding to port 22000 (The port used by impala daemons to communicate with each other.)

Symptoms show:

1. The impala daemon tries to start but ends up giving the following error as seen in /var/log/impalad on the node.  From /var/log/impalad ERROR file:

Log file created at: 2016/03/02 15:14:06
Running on machine:
Log line format: [IWEF]mmdd hh:mm:ss.uuuuuu threadid file:line] msg
E0302 15:14:06.033330 13908] stderr will be logged to this file.
E0302 15:14:08.167940 14031] ThriftServer 'backend' (on port: 22000) exited due to TException: Could not bind: Transport endpoint is not connected
E0302 15:14:08.168010 13908] ThriftServer 'backend' (on port: 22000) did not start correctly
E0302 15:14:08.168669 13908] ThriftServer 'backend' (on port: 22000) did not start correctly

2. It is observed that the impala daemon itself is using the port on this host, not another process.  If the daemon is killed another one starts and uses the port.
