Steve Loughran created HADOOP-9651:
--------------------------------------
Summary: Filesystems to throw FileAlreadyExistsException in
createFile(path, overwrite=false) when the file exists
Key: HADOOP-9651
URL: https://issues.apache.org/jira/browse/HADOOP-9651
Project: Hadoop Common
Issue Type: Sub-task
Components: fs
Affects Versions: 2.1.0-beta
Reporter: Steve Loughran
Priority: Minor
While HDFS and other filesystems throw a {{FileAlreadyExistsException}} if you
try to create a file that exists and you have set {{overwrite=false}},
{{RawLocalFileSystem}} throws a plain {{IOException}}. This makes it impossible
to distinguish a create operation failing from a fixable problem (the file is
there) and something more fundamental.
