Do I need zookeeper ?

[#1]

Is Zookeeper required if HBase is NOT used?

[#2 · Accepted solution]

Hi MB,

Yes, Zookeeper is used by a lot of components (for High Availability purpose), not only HBase. It is a mandatory and vital component.

Maybe.

ZooKeeper is used for a variety of systems in HDP for high-availability and distributed locking scenarios. For example, high-availability in HDFS with automatic failover requires ZooKeeper.
