> {{FileTargetImplTest.testHandleOutputsMovesFilesToDestination}} consistently fails on
my machine because it relies on the erroneous assumption that {{handleOutputs}} will preserve
part indexes in file names.
> If you are lucky the {{part-m-00000}} file created by the MR job will be copied to the
destination folder with the exact same name. However it just... luck. Final index only depends
on  iterator order which can vary from machine to machine (OS, FS, JDK etc.)
> This test should be rewritten to not rely on a such erroneous assumption.
