Wei Yan created HDFS-13198:
------------------------------

             Summary: RBF: RouterHeartbeatService throws out CahcedStateStore related exceptions
when starting router
                 Key: HDFS-13198
                 URL: https://issues.apache.org/jira/browse/HDFS-13198
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Wei Yan
            Assignee: Wei Yan


Exception looks like:
{code:java}
2018-02-23 19:04:56,341 ERROR router.RouterHeartbeatService: Cannot get version for class
org.apache.hadoop.hdfs.server.federation.store.MembershipStore: Cached State Store not initialized,
MembershipState records not valid

This is because, during starting the Router, the CachedStateStore hasn't been initialized
and cannot serve requests. Although the router will still be started, it would be better to
fix the exceptions.
