Description

When trying to download a file though the new Namenode UI FS Browser, the browser doesn't know the name of the file because of a trailing slash. For instance, this url is broken and Firefox picks a random name for:

http://dn.example.com:70/webhdfs/v1/user/tthompso/test_examples/wordcount_in/core-site.xml/?op=OPEN&delegation=TOKEN&namenoderpcaddress=namenode.example.com:9000&offset=0

But if you remove the trailing / on the file name, Firefox correctly picks up the name of the file:

http://dn.example.com:70/webhdfs/v1/user/tthompso/test_examples/wordcount_in/core-site.xml?op=OPEN&delegation=TOKEN&namenoderpcaddress=namenode.example.com:9000&offset=0
