commons-codes and commons-lang3 from flink-table
URL: https://github.com/apache/flink/pull/6863#issuecomment-430518728
Hi @leanken . Thank you for your contribution. I am afraid though it is not
the right way to proceed with this bug. I think we should rather cut off usage
of `Base64` (replace with our own implementation) than add hard external
dependencies.
Also just to clarify why we relocate dependencies. The reason is not just so
they do not clash with other dependencies of ours (e.g. from calcite as you
said), but also so that Flink's users can use any arbitrary version of popular
libraries.
