> Key: HDFS-12101
> URL: https://issues.apache.org/jira/browse/HDFS-12101
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.8.1
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Attachments: HADOOP-14630-001.patch

>
> HADOOP-14630 adds some contract tests trying to create files or rename files
> *under other files*.
> On a rename under an existing file (or dir under an existing file), HDFS
> fails throwing
> {{org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.fs.ParentNotDirectoryException)}}.
>
> # is throwing an exception here what people agree is the correct behaviour?
> If so, it can go into the filesystem spec, tests set up to expect it. object
> stores tweaked for consistency. If not, HDFS needs a change.
> # At the very least, HDFS should be unwrapping the exception.
