Subject [jira] [Created] (ACCUMULO-3557) No write ACL set on /accumulo/instances/...
Date Tue, 03 Feb 2015 15:52:36 GMT
Josh Elser created ACCUMULO-3557:
------------------------------------

             Summary: No write ACL set on /accumulo/instances/...
                 Key: ACCUMULO-3557
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3557
             Project: Accumulo
          Issue Type: Improvement
          Components: zookeeper
            Reporter: Josh Elser
            Priority: Critical
             Fix For: 1.7.0


It's common for users to have four "arguments" to make a connection to Accumulo: zookeeper
quorum string, instance name, username and password.

The instance name is used to find the instanceID using {{/accumulo/instances/...}} in ZooKeeper.
It appears that anyone can write in the {{/accumulo/instances}} ZNode. This seems suspect,
because any unauthenticated user can alter the state of ZooKeeper and break users connecting
to Accumulo or force them to connect to a different Accumulo instance.
