Thanks for pointing me to the `distcp` page. So far, I was agnostic of this
tool :) The performance difference between Hadoop and Flink should not be too
different because the copying of files is mostly IO-bound work. Still, it is
1.5 minutes faster.
Not sure if we can include your code in the Flink examples but definitely
under `flink-contrib` where we usually put external tools that are not directly
part of Flink.
