Todd Lipcon updated HDFS-4997:

Release Note: libhdfs now returns correct codes in errno. Previously,
due to a bug, many functions set errno to 255 instead of the more specific
error code.
Hadoop Flags: Incompatible change,Reviewed
> libhdfs doesn't return correct error codes in most cases

> Key: HDFS-4997
> URL: https://issues.apache.org/jira/browse/HDFS-4997
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: libhdfs
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Attachments: HDFS-4997.001.patch
>
>
> 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.
