Thank you again. :) I ran the delete, but I'm not sure if it did anything:
root> ./opt/cloudera/parcels/CDH-5.1.3-1.cdh5.1.3.p0.12/lib/zookeeper/bin/zkCli.sh -server myhost.mydomain.com:2181 delete /controller Connecting to myhost.mydomain.com:2181 WATCHER:: WatchedEvent state:SyncConnected type:None path:null root> I followed that up immediately by an "ls /", and the controller znode was there. Either still there, or had already been re-created. There was nothing in the Kafka logs indicating that anything had happened either, so I'm thinking maybe I need to try and delete the znode partition manually? Or, should I have seen the controller znode disappear for a time? Very much appreciate your help! Chris On Sun, May 17, 2015 at 1:33 PM, Clark Haskins <cl...@kafka.guru> wrote: > Yeah it's empty.
