------------------------------------------
Hi Karl,
Not sure how others are deploying but our cluster which is used in conjunction
with ManifoldCF also contains HBase and Hadoop-HA (v2 of Hadoop allows you to
use Zookeeper as a fencing mechanism) nodes. Given that we start with 4
separate slices, I deploy a single 3-node Zookeeper ensemble which is shared
between all of the services (for redundancy).
Can you point me at any references regarding the performance costs of a
hierarchy of znodes?

> Key: CONNECTORS-921
> URL: https://issues.apache.org/jira/browse/CONNECTORS-921
> Project: ManifoldCF
> Issue Type: Improvement
> Components: Framework core
> Affects Versions: ManifoldCF 1.6
> Reporter: Graeme Seaton
> Assignee: Graeme Seaton
> Priority: Minor
> Fix For: ManifoldCF 1.6

>
> The nodes created in Zookeeper by MCF are created directly beneath the root.
> This can make it difficult to find the nodes for other applications. There
> seems to be a convention to create an application node under the root (based
> on Hbase and Hadoop usage).
> I would like to create a manifoldcf 'parent' and place all of the nodes
> within it. It might also make sense to create 'parent' nodes for each of the
> PATH_PREFIXES.
