[jira] [Commented] (FLINK-3337) mvn test fails on flink-runtime
because curator classes not found
[ https://issues.apache.org/jira/browse/FLINK-3337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15134328#comment-15134328 ]
Robert Metzger commented on FLINK-3337:
---------------------------------------
I wonder if this commit caused the issue: https://github.com/apache/flink/commit/7378f014bbb3f99dbe73697926aff485d399be5a
Did you rebuild the entire flink project before?
Our tests on travis are passing, so I guess its just a local mixup
