Chesnay Schepler updated FLINK-12902:
-------------------------------------
    Description: 
The dependency situation in this module is just insane; you have a few unshaded 
hadoop dependencies from `flink-yarn-tests`, some shaded hadoop dependencies 
from `flink-shaded-yarn-tests` and _yet another_ set of shaded hadoop 
dependencies from `flink-shaded-hadoop`. All of these are available on the test 
classpath, resulting in what is effectively an incomprehensible classpath.

This is highlighted in the shading patterns in `flink-shaded-yarn-tests`, which 
absolutely had to be in sync with `flink-shaded-hadoop` as otherwise you ended 
up with strange `VerifyErrors`.

  was:
flink-shaded-yarn relocates a few dependencies that are later used by 
flink-yarn-tests. Currently the relocations applied must be in sync with 
flink-shaded-hadoop _for some reason_.

We should find out why they have to be in sync.
