Kihwal Lee reopened HDFS-7816:
------------------------------
Assignee: (was: Brahma Reddy Battula)
HDFS-6662 only partially fixes the problem. The decoding is done by calling
{{decodeComponent()}}, which decodes "+" as a space. A "+" sign in query string
should be decoded as a space, but not if in the path.
For proper decoding of path, we can create a {{URI}} object with the encoded
string and then call getPath(), which only decodes "%", not "+".

> Issue Type: Bug
> Components: webhdfs
> Affects Versions: 2.7.0
> Reporter: Jason Lowe
> Priority: Blocker
>
> webhdfs requests to open files with % characters in the filename fail because

> cat: File does not exist: /user/somebody/abc%25def
