             Summary: Update Hadoop RPC Encryption Properties During Kerberization and Upgrade
                 Key: AMBARI-22725
                 URL: https://issues.apache.org/jira/browse/AMBARI-22725
             Project: Ambari
          Issue Type: Task
    Affects Versions: 2.6.2
            Reporter: Jonathan Hurley
            Priority: Critical
             Fix For: 2.6.2


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.
