Subject RE: Disconnect between Accumulo instances seen by Zookeeper and Accumulo
Date Mon, 16 Sep 2013 19:05:42 GMT
Thanks John.

I confirmed that all of my accumulo-site.xml files have the same list of Zookeeper instances
for So that led me to wonder about consistency. I decided to see
if all of the Zookeeper nodes match. They don't.

Two of the zookeeper nodes do not have any /accumulo path. One does. So Accumulo must be answering
based on one or both of the Zookeeper nodes that do not have a /accumulo path and not based
on the one with the path. I'm not sure how Zookeeper got into this state. Any ideas on how
to fix it?

Using ListInstances uses the defined zookeepers from accumulo-site.xml. If you have accumulo-site.xml
pointing at a different set of ZooKeepers you will see the behavior your experiencing.

What would cause a situation where Zookeeper shows Accumulo instances but Accumulo lists no

Executing an ls /accumulo/instances using I can see two instances listed.
Using bin/accumulo org.apache.accumulo.server.util.ListInstances I see none listed.

I'm running CDH4.3 and Accumulo 1.4.3.
