Tim Armstrong commented on IMPALA-4057:
---------------------------------------
I think this is a minor bug in impala_cluster.py - it assumes that the
webserver will be listening on whatever socket.gethostname() maps to. For this
to work generally, since you can get the webserver to listen on any interface,
we'd need to plumb through the webserver port to the code that polls the
webserver, or try all of the interfaces on the localhost.
> Start webserver with interface"127.0.0.1" failed.
