> *Given HTTP port instead of RPC port In following sentence*
> HFTP is primarily useful if you have multiple HDFS clusters with different
> versions and you need to move data from one to another. HFTP is
> wire-compatible even between different versions of HDFS. For example, you can
> do things like: *{color:red}hadoop distcp -i hftp://sourceFS:50070/src
> hdfs://destFS:50070/dest{color}* . Note that HFTP is read-only so the
> destination must be an HDFS filesystem. (Also, in this example, the distcp
> should be run using the configuraton of the new filesystem.)
> *Expected:*
> {color:green}hdfs://destFS:<RPC PORT>/dest{color}
