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

Exception looks like:
{code:java}

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.
