URL encoding of directories about hdfs

[mtth]

Thanks for pointing this out. Let me know if you know of any special characters other than = that we shouldn't be encoding. I'll push a fix to stop encoding them (reserved characters usually need to, see #11).

= won't be encoded after 6581150 (version >=1.0.1). Feel free to reopen if you need other characters.

Awesome! Thanks!

Off the top of my head, I can't think of any other characters that would be affected by this.

I am having the same issue for directory names containing german special characters: ä,ö,ü,ß,Ä,Ö,Ü. Maybe you could include these characters also.
