When I do hadoop mfs -ls /somedir

The output looks like
permission Z U - user group blocks? date size path ...

What does Z and U mean together? I know Z is compressed and U is uncompressed but not sure what they mean together. This is true for all folders including /. When I do hadoop mfs -setcompression on it has no effect.
