save rdd with gzip compresson but without .gz extension?

[Alexander Pivovarov]

Question #1
When spark saves rdd using Gzip codec it generates files with .gz extension.
Is it possible to ask spark not to add .gz extension to file names and keep
file names like part-xxxxx

I want to compress existing text files to gzip and want to keep original
file names (and context)


Question #2.
is it possible to not produce crc files? e.g. .part-xxxxx.gz.crc and
._SUCCESS.crc
