Description

YARN has an implicit dependency on ZOOKEEPER. It currently didn't declare an explicit dependency because HDFS had one.

Enabling the following settings in YARN requires ZOOKEEPER:

• yarn.resourcemanager.recovery.enabled
• yarn.nodemanager.recovery.enabled
• yarn.resourcemanager.ha.enabled
• hadoop.registry.rm.enabled

In addition, these properties are related to ZOOKEEPER and should be empty if ZOOKEEPER is not installed:

• yarn.resourcemanager.zk-address
• hadoop.registry.zk.quorum
