Maximilian Michels updated FLINK-3864:
--------------------------------------
    Description: {{YarnTestBase.runWithArgs(...)}} provides a parameter for 
strings which must not appear in the log output. {{perJobYarnCluster}} and 
{{perJobYarnClusterWithParallelism}} have "System.out)" prepended to the 
prohibited strings; probably an artifact of an older test code.  (was:

Turns out, the intended check doesn't hold anymore. The Yarn cluster doesn't 
set the maximum parallelism for a per-job cluster. It always uses parallelism 
1.)
