Subject [jira] [Commented] (HADOOP-8215) Security support for ZK Failover controller
Date Tue, 03 Apr 2012 23:38:24 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245892#comment-13245892

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
