Chesnay Schepler updated FLINK-7288:
------------------------------------
    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.
