[jira] [Commented] (KAFKA-797) Cannot start Kafka 0.8 per Quick Start instructions

    [ https://issues.apache.org/jira/browse/KAFKA-797?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13627740#comment-13627740 ]

David Arthur commented on KAFKA-797:
------------------------------------

Not sure if anything actually changed, but this works for me now. For me, it turned out to be an issue with SBT and Ivy. I cleared ~/.ivy2/cache/org.scala* and ~/.ivy2/cache/scala* and things started working again.
