Description

"yarn.resourcemanager.zk-address" was deprecated in 2.9.x and moved to "hadoop.zk.address". However this doesn't appear in Deprecated Properties.

Additionally, the Configuration base class doesn't auto-translate from "yarn.resourcemanager.zk-address" to "hadoop.zk.address". Only the sub-class YarnConfiguration does the translation.

Also, the 2.9+ Resource Manager HA documentation still refers to the use of "yarn.resourcemanager.zk-address".
