             Summary: [RBF] The routers should be resiliant against exceptions from StateStore
                 Key: HDFS-16844
                 URL: https://issues.apache.org/jira/browse/HDFS-16844
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: rbf
    Affects Versions: 3.3.4
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently, a single exception from the StateStore will cripple a router by clearing the caches before the replacement is loaded. Since the routers have the information in an in-memory cache, it is better to keep running. There is still the timeout that will push the router into safe-mode if it can't load the state store over a longer period of time.
