> HDFS-13541 implemented based selective encryption in the Namenode. 
> {noformat}
> This feature allows HDFS to selectively enforce encryption for both RPC (NameNode) and data transfer (DataNode).
> With this feature enabled, NameNode can listen on multiple ports, and different ports can have different security 
> configurations. Depending on which NameNode port clients connect to, the RPC calls and the following data transfer
> will enforce security configuration corresponding to this NameNode port. This can help when there is requirement
> to enforce different security policies depending on the location where the clients are connecting from.
> {noformat}
> This ability for selective encryption should still be available to clients when they connect to routers instead of directly to the namenode.
> This implemented can leverage a lot of the code written for the Namenode selective port based encryption. A lot of the changes are in hadoop-common, eg. HDFS-13566.
