Subject [jira] [Commented] (HADOOP-8215) Security support for ZK Failover controller
Date Tue, 03 Apr 2012 22:34:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245839#comment-13245839
] 

Aaron T. Myers commented on HADOOP-8215:
----------------------------------------

Patch looks pretty good, Todd. Just a few little nits. +1 once these are addressed.

# Typo: "partiall borrowed from"
# Please add a comment to the public method HAZKUtil#parseAuth.
# In a few test methods you expect exceptions to be thrown but then just silently ignore them.
Should probably put some GenericTestUtil#verifyExceptionContains in there.

> 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
