Subject [jira] [Commented] (HDFS-3893) QJM: Make QJM work with security enabled
Date Thu, 06 Sep 2012 21:36:08 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450069#comment-13450069
] 

Aaron T. Myers commented on HDFS-3893:
--------------------------------------

To be explicit, it is not the case that one needs a value for the new ACL set in hadoop-policy.xml.
It is the case, however, that we do need to have an ACL for this protocol. That's taken care
of by the change in HDFSPolicyProvider that's in this patch.

> Currently the QJM does not work when security is enabled. The quorum cannot be formatted,
the NN and SBN cannot communicate with the JNs, and JNs cannot synchronize edit logs with
each other.
