Description
If the federation has no subclusters the logs have long stack traces. Even though this is not a regular setup for RBF, we should trigger log message.
An example:
Caused by: java.lang.IndexOutOfBoundsException: Index: 0, Size: 0 at java.util.LinkedList.checkElementIndex(LinkedList.java:555) at java.util.LinkedList.get(LinkedList.java:476) at org.apache.hadoop.hdfs.server.federation.router.RouterRpcClient.invokeConcurrent(RouterRpcClient.java:1028) at org.apache.hadoop.hdfs.server.federation.router.RouterRpcServer.getDatanodeReport(RouterRpcServer.java:1264) at org.apache.hadoop.hdfs.server.federation.metrics.FederationMetrics.getNodeUsage(FederationMetrics.java:424)
