Can someone please direct me to good resources in understanding Zookeeper's
role in Hbase system ?
One in official guide does not explain it in detail.

For further more detail I wonder possibly the best way should be reading the source code:-), not sure if there are comprehensive wiki/blog for such details you need...

A rough answer to this question (not necessarily comprehensive)
1. store root region's location
2. help select active master
3. help monitor regionservers' health
4. help table tasks such creating/deleting/enabling/disabling
5. help region-in-transition tasks such as assign/unassign/split/merge (store task status)
6. coordinate/dispatch hlog split tasks during regionserver failover
7. store replication configuration such as whether replication is enabled, peer configuration and setting, and etc
8. store cluster-id
