Github user mjsax commented on the pull request: https://github.com/apache/flink/pull/750#issuecomment-135523032 I just pushed three commits on top addressing your comment. The first two, include reworking all test cases in a whole package each, to change the test pattern from "catch -> print StackTrace -> fail" to "don't-catch and fail directly". This changes include a few other clean up tasks in those test. Of course I run the test without error. But please review carefully to make sure I did not break anything.
