> When testing MapReduce on top of an HA cluster we ran into the following bug:
> some uses of HDFS paths go through a canonicalization step which ensures that
> the authority component in the URI includes a port number. So our
> hdfs://logical-nn-uri/foo path turned into hdfs://logical-nn-uri:8020/foo.
> The code which looks up the failover proxy provider then failed to find the
> associated config. We should only compare the hostname portion of the URI
> when looking up proxy providers.
