Hello, I have setup redundancy on resource manager based on this doc https://hadoop.apache.org/docs/r2.4.1/hadoop-yarn/hadoop-yarn-site/ResourceManagerHA.html I then shut down server 1 and was expecting that 02 server would take over.
Instead I see this error. I am not sure if I am missing something. 2015-05-14 11:55:01,820 INFO [Node Status Updater] retry.RetryInvocationHandler (RetryInvocationHandler.java:invoke(140)) - Exception while invoking nodeHeartbeat of class ResourceTrackerPBClientImpl over rm2 after 19 fail over attempts.
