Íñigo Goiri created HDFS-13410: ---------------------------------- Summary: RBF: Support federation with no subclusters Key: HDFS-13410 URL: https://issues.apache.org/jira/browse/HDFS-13410 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Íñigo Goiri Assignee: Íñigo Goiri
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: {code} 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) {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
