Sergey Nuyanzin commented on FLINK-39002:
-----------------------------------------
Ok, seems not related to flink-shaded upgrade
I noticed that release-2.0 branch is failining with same reason
https://dev.azure.com/apache-flink/apache-flink/_build/results?buildId=71964&view=logs&j=af184cdd-c6d8-5084-0b69-7e9c67b35f7a&t=0f3adb59-eefa-51c6-2858-3654d9e0749d&l=4755
looks like azure related problem...
