My ZK directory listing is as below. Looks like offsets path is not even created.
zk: localhost:2181(CONNECTED) 0] ls / [hadoop-ha, hbase, zookeeper, consumers, controller, storm, brokers, controller_epoch] [zk: localhost:2181(CONNECTED) 1] ls /consumers [1, das-service] [zk: localhost:2181(CONNECTED) 2] ls /consumers/1 [owners, ids] [zk: localhost:2181(CONNECTED) 3] ls /consumers/1/offsets Node does not exist: /consumers/1/offsets [zk: localhost:2181(CONNECTED) 4] On Thu, May 23, 2013 at 7:08 AM, Jun Rao <jun...@gmail.com> wrote: > You are looking at the wrong path in ZK.
