> When *HDP 3.0.0* is installed, 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.
