Description

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
