------------------------------------
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.
