It does this by concurrently trying all namenodes and picks the namenode that returns the fastest with a successful response as the active node. > It would be useful to have a similar ProxyProvider for the Yarn RM (it can possibly be done by converging some the class hierarchies to use the same ProxyProvider) > This would especially be useful for large YARN deployments with multiple standby RMs where clients will be able to pick the active RM without having to traverse a list of configured RMs. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
