"Exploring zookeeper"
4.5/5
What do you like best about ZooKeeper?

Zookeeper is a very useful service as I was using this with Hadoop where it manages the node and see whether the node is alive or not. If not, it assigns to the secondary available node that helps us a lot not worry about the cluster maintenance. Review collected by and hosted on G2.com.

What do you dislike about ZooKeeper?

Zookeeper, however, helps us in many ways but some things that I don't like are that it is very slow and waits for the response of the node for a certain period, which wastes my time for switching the node. Review collected by and hosted on G2.com.
