---------------------------------
I came across the same error:
*Error Message*

And I agree with [~cnauroth]'s speculation regarding the race condition. Patch
002 added the {{join}} method. I'm having a hard time reproducing the issue
though, mainly because of the difficulty of reaching the BindException in
jetty, so no unit test added.
As a side note, setting {{DFS_NAMENODE_HTTP_ADDRESS_KEY}} at the beginning
would not work, because in {{NameNodeHttpServer#start}}, we {{conf.set}} it to
the address (including port) of the open connection. So when later in the test
where {{cluster.restartNameNode}}, this configuration is read and will be used
to start the http server. I feel no change is needed in this test since the RC
is on the connection side anyways.
