ASF GitHub Bot commented on FLINK-6836: --------------------------------------- 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`. > Failing YARNSessionCapacitySchedulerITCase.testTaskManagerFailure > ----------------------------------------------------------------- > > Key: FLINK-6836 > URL: https://issues.apache.org/jira/browse/FLINK-6836 > Project: Flink > Issue Type: Bug > Components: Tests, YARN > Affects Versions: 1.4.0 > Reporter: Till Rohrmann > Assignee: Till Rohrmann > Priority: Critical > Labels: test-stability > > The master is currently unstable.
