Subject [jira] [Created] (HDFS-3090) Broaden NN#monitorHealth checks
Date Wed, 14 Mar 2012 04:53:53 GMT
Broaden NN#monitorHealth checks 

                 Key: HDFS-3090
                 URL: https://issues.apache.org/jira/browse/HDFS-3090
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 0.23.3
            Reporter: Eli Collins

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).
