-----------------------------------
[~azagrebin] I'm not working on this. Here is the change set where I notice
this test fails
https://github.com/apache/flink/compare/965e4e58a354...79e3b32b4ae9 . IMO the
change is safe so that I file a JIRA to report unstable test. I don't have a
patch to reproduce it also.
