https://github.com/apache/flink/pull/2708
@uce @mxm after adding the recursive wildcard the nested jar files are
copied to the application directory within HDFS. This is my first time testing
Flink on YARN and I am getting a `ClassNotFoundException` from a class within
the `flink-gelly` jar even when it is copied to `lib` (not nested).
