Subject [jira] [Commented] (HBASE-13768) ZooKeeper znodes are bootstrapped with insecure ACLs in a secure configuration
Date Sat, 30 May 2015 01:08:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13768?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14565744#comment-14565744
] 

Matteo Bertozzi commented on HBASE-13768:
-----------------------------------------

sorry, i'm late on this one. 
but since we have the checkAndSetZNodeAcls() why are we covering only the 
unsecure -> secure case and not the other way around too?
it is just matter of skipping the early exit in checkAndSetZNodeAcls() if !isSecureZooKeeper()
and 
when we call ZKUtil.createACL() instead of forcing true we pass isSecureZooKeeper()
and adjust the isBaseZnodeAclSetup() to check for the unsecure case.
so with the same thing, we cover also the secure -> unsecure case.
(otherwise we have to use the tool HBASE-13162 for this specific case)

> A logic error causes HBase in most secure configuration deployments to handle its coordination
state in ZooKeeper via insecure ACLs. Anyone with remote unauthenticated network access to
the ZooKeeper quorum, which by definition includes all HBase clients, can make use of this
opening to violate the operational integrity of the system. For example, critical znodes can
be deleted, causing outages. It is possible to introduce rogue replication endpoints. It is
possible to direct the distributed log splitting facility to split arbitrary files in HDFS.
