Description

The YarnClusterDescriptor and org.apache.flink.yarn.Utils contain testing code which is to work around an issue with the Kerberos authentication when running the YARN integration tests. The respective code is YarnClusterDescriptor.java:840-858;936-942, Utils.java:445+,478+.

Eron pointed this already out in the initial PR which introduced this code. We should try to remove this code, if possible.
