Robert Metzger commented on FLINK-11086:
----------------------------------------
Implementation plan:
- wait for decision on the dev@ ml
- replace all flink-shaded-hadoop-* dependencies with vanilla dependencies
- remove shading from flink-swift-fs-hadoop (update docs)
- test flink with hadoop manually
- update documentation on how to use flink with hadoop
> Add support for Hadoop 3
