it seems like a "repartition" on a "gz" file doesn't work. I unzipped the "gz" directly in hdfs, and rebuilt a dataframe on it => now I can change the number of partitions, and see faster results.

It will work, fine but it happens after loading. First stage won't be affected.

I couldn't really repartition a gz files. I had to transform it on csv to get partioning working correctly.
