Access datasources, pipelines, Solr collection configs via Zookeeper

Goal:

How can I access data which is stored about the Fusion datasources, pipelines, Solr collection configs via Zookeeper? 

Environment:

Fusion 4.x, Zookeeper

Guide:

All Fusion app configurations like datasources, pipelines reside in the zookeeper . You can either modify them via Fusion UI or you need to access them via zookeeper .

Access configs via Zookeeper

1. Go to the bin folder of fusion.
2. Run the ./zookeeper-client script in that folder

3. You need to go under the respective zookeeper chroot to access collections.  As an example in Fusion 4.2.6:

[zk: localhost:9983(CONNECTED) 2] ls /lwfusion/4.2.6/core

The core contains fusion objects such as connectors, query-pipelines, job-schedules, and more.

[zk: localhost:9983(CONNECTED) 3] ls /lwfusion/4.2.6/solr

This solr zookeeper "zookeeper node" (a directory, not an instance of zookeeper) contains solr objects such as configs, live_nodes, collections, clusterstate.json, and more.

If you are instead running zkcli on a separate instance, such as a local machine from which you obtained the zookeeper CLI script, you will use the -server flag to indicate where to connect:

> ./zkCli.sh -server fusionHost:2181
