Github user wesm commented on the issue: https://github.com/apache/zeppelin/pull/1574 In trying to investigate why the Apache Travis CI build queue is extremely backlogged, I found many build requests from this particular PR in https://travis-ci.org/apache/zeppelin/pull_requests Since this project's build matrix has 11 entries, this can pretty easily jam up the build queue for other projects. I created https://issues.apache.org/jira/browse/INFRA-13469 in an attempt to mitigate this problem in the future
