> Clients should have the ability to choose encrypted communication over RPC when talking
to core hadoop components. Today, the properties that control this are:
>  - {{core-site.xml : hadoop.rpc.protection = authentication}}
>  - {{hdfs-site.xml : dfs.data.transfer.protection = authentication}}
> The new value of {{privacy}} enables clients to choose an encrypted means of communication.
By keeping {{authentication}} first, it will be taken as the default mechanism so that wire
encryption is not automatically enabled by accident.
> The following properties should be changed to add {{privacy}}:
>  - {{core-site.xml : hadoop.rpc.protection = authentication,privacy}}
>  - {{hdfs-site.xml : dfs.data.transfer.protection = authentication,privacy}}
> The following are cases when this needs to be performed:
>  - During Kerberization, the above two properties should be automatically reconfigured.
>  - During a stack upgrade to any version of HDP 2.6, they should be automatically merged
> Blueprint deployment is not a scenario being covered here.
