Security support for ZK Failover controller
-------------------------------------------
Key: HADOOP-8215
URL: https://issues.apache.org/jira/browse/HADOOP-8215
Project: Hadoop Common
Issue Type: Improvement
Components: ha, security
Affects Versions: 0.23.3, 0.24.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
To keep the initial patches manageable, kerberos security is not currently
supported in the ZKFC implementation. This JIRA is to support the following
important pieces for security:
- integrate with ZK authentication (kerberos or password-based)
- allow the user to configure ACLs for the relevant znodes
- add keytab configuration and login to the ZKFC daemons
- ensure that the RPCs made by the health monitor and failover controller
properly authenticate to the target daemons
