Todd Lipcon reopened HDFS-2979:
-------------------------------
This patch seems to have made some tests fail (I noticed with TestFileAppend2).
It seems to be trying to connect to 127.0.0.1:0 instead of the correct port.
> HA: Balancer should use logical uri for creating failover proxy with HA
> enabled.

> Presently Balancer uses real URI for creating the failover proxy.
> Since the failover proxy checks for uri consistency, we should pass logical
> uri for creating failover proxy instead of instead of real URI. Presently
> will work only with default port.
> java.io.IOException: Port 49832 specified in URI hdfs://127.0.0.1:49832 but
> host '127.0.0.1' is a logical (HA) namenode and does not use port information.
