[jira] [Commented] (SPARK-7538) Kafka stream fails:
java.lang.NoClassDefFound com/yammer/metrics/core/Gauge
[ https://issues.apache.org/jira/browse/SPARK-7538?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14538613#comment-14538613 ]
Sean Owen commented on SPARK-7538:
----------------------------------
This usually indicates classpath problems with the app. Are you using a dependency, like this metrics lib, that might be conflicting? I think streaming does, so that might be why it shows up in streaming. Did you try setting the user classpath first settings?
