Sean Mackrory commented on HADOOP-15860:
----------------------------------------

Attaching a patch with a test that reproduces the issue. In this case, the 
behavior for files and directories is actually identical, so I suspect the 
nuances I was seeing was just a case of the FsShell not using the same APIs for 
similar operations on each. Note that in this test, the assertion that the file 
/ directory exists succeeds, but they are both missing from lists because the 
paths are missing periods. So this may just be a bug in listing.

> ABFS: Trailing period in file names gets ignored for some operations.

> If you create a directory with a trailing period (e.g. '/test.') the period 
> is silently dropped, and will be listed as simply '/test'. '/test.test' 
> appears to work just fine.
