[jira] [Commented] (FLINK-2163) VertexCentricConfigurationITCase
sometimes fails on Travis
[ https://issues.apache.org/jira/browse/FLINK-2163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14572903#comment-14572903 ]
Ufuk Celebi commented on FLINK-2163:
------------------------------------
I think I/O on Travis is unreliable. We could fix these problems by using collect() instead of writing to a file (and then comparing the file with the expected result). This will also result in more test exposure for the collect call ;) and we can be sure that the result is really off.
