    [FLINK-3735] Make DataSetUnionRule match only for union-all

    Currently `UnionToDistinctRule` converts all unions to union-all + distinct, so this is just an extra check to make sure that unions are not translated in case the rule is removed or won't match.

You can merge this pull request into a Git repository by running:

    $ git pull https://github.com/vasia/flink union-all
