-------------------------------------
Summary: DFSClient.rename() to unwrap ParentNotDirectoryException;
define policy for renames under a file
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
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.
