> *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}
