    Description

      Currently the NN implementation of HAServiceProtocol#monitorHealth just calls FSNamesystem#checkAvailableResources. We should extend this method to cover a broader range of resources (eg HDFS-2704), but we should also extend NN#monitorHealth to make other unrelated health checks (eg whether all its important service threads are running, memory usage, etc).
