----------------------------------------
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.
