Colin Patrick McCabe commented on HDFS-4997:
--------------------------------------------
The release audit warning is about a lingering pid file, so it's a Jenkins
issue, not a patch issue.
The JavaDoc warning is also bogus given that it refers to a negative number of
additional warnings, and this change only touches .c files.
Will commit shortly. Thanks, Todd.

>
> libhdfs has some code to translate Java exceptions into C error codes.
> Unfortunately, the exceptions are returned to us in "dotted" format, but the
> code is expecting them to be in "slash-separated" format. This results in
> most exceptions just leading to a generic error code.
> We should fix this and add a unit test to ensure this continues to work.
