Also, I've disabled the test for flip6 mode in order to make the test pass.
Can you explain a bit on why this code block
(https://github.com/apache/flink/blob/25ac971d39e0ed58965334a6735396d5d10e7278/flink-yarn-tests/src/test/java/org/apache/flink/yarn/YARNSessionFIFOITCase.java#L102)
is disabled in flip6 mode? I can create another JIRA to address the issue in
flip6 mode.---
