Todd Lipcon commented on HADOOP-8215:
-------------------------------------
I'll commit this momentarily to the branch based on ATM's above +1, since the
review feedback changes were mostly cosmetic. I ran the ZKFC and HAAdmin tests
locally for both common and HDFS and they passed.

> 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
