Rui Li commented on FLINK-1640:
-------------------------------
Hi [~fhueske], I noticed in this PR we trim trailing whitespaces when creating
a Path. Therefore I cannot create paths like {{'/my/path/ '}}, which is
supported in Hadoop. Is there any reason why we have to trim the whitespaces
(there's test case in {{PathTest}} to verify this behavior)?
BTW, I'm asking because it causes some problem like FLINK-16532.

> The FileOutputFormat duplicates the last directory of a path, if the path
> ends with a slash '/'.
