> Had a test failure last night in KerberosProxyIT. It seems the following
> happened
> # Bind a server socket using '0' (pull a free port from the ephemeral range)
> # Determine the actual port which was bound
> # Close the socket
> # Another process grabbed the port we had bound
> # Attempt to start the proxy on that port
> The proxy failed to start because the port we provided was already taken.
> This stems from a problem that we can't have the Proxy bind to any free port
> and figure out where it started (what port it actually bound); maybe we could
> provide configuration to advertise this in ZooKeeper (will file another
> issue). For this test, if we fail to connect to the proxy and the proxy is
> dead, we can try to re-start the proxy with a different port. Given how rare
> this scenario is, hopefully retrying it takes the chance it happens again to
> effectively 0%.
