>
> This is a request to do some cosmetic improvements on top of HDFS-8480. There
> a couple of File -> java.nio.file.Path conversions which is a little bit
> distracting.
> The second aspect is more around efficiency, to be perfectly honest I'm not
> sure what the number of files that may be processed. However as HDFS-8480
> eludes to it appears that this number could be significantly large.
> The current implementation is basically a collect and process where all files
> first is being examined; put into a collection and after that processed.
> HDFS-8480 could simply be further enhanced by employing a single iteration
> without creating an intermediary collection of filenames by using a FileWalker
