Github user tillrohrmann commented on the issue:
https://github.com/apache/flink/pull/4120
I first thought I had to downgrade, because of the aforementioned problem.
However, Hadoop 2.8.0 needs at least httpclient `4.5.2`. Luckily, they fixed
the problem with the `URLEncodedUtils#parse` method in `4.5.3`. Therefore I
bumped the version again.
Concerning moving the dependency management to `flink-shaded-hadoop`: I
think this is unfortunately not possible since due the immutable reactor builds
from maven, `flink-yarn-tests` pulls all dependencies from
`flink-shaded-hadoop` and `flink-shaded-yarn-tests`. This also means that
depending on the classpath order, we either use the shaded Yarn mini-cluster or
not. In the latter case we have to make sure that we are using `httpclient`
`4.5.3` which is only the case if we define the dependency management in the
parent pom.
As a side remark, given this situation with maven, I'm not sure whether we
actually need the `flink-shaded-yarn-tests` module.
A proper solution would be fixing the problem with the immutable builds.
For example, everything works properly if we first install the shaded jars and
then build the flink-yarn-tests. Then maven will properly resolve all
dependencies. In this case, I think it should be possible to move the
dependency management into `flink-shaded-hadoop`.
