Subject [jira] [Commented] (HADOOP-9651) Filesystems to throw FileAlreadyExistsException in createFile(path, overwrite=false) when the file exists
Date Mon, 08 Jul 2013 10:21:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9651?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13701916#comment-13701916

Steve Loughran commented on HADOOP-9651:
----------------------------------------

Core patch looks good, though you need to make sure that your IDE isn't turning imports into
.* imports -having them leave all imports alone is the best way to avoid gratuitous diff/merge
problems.


I'll add common contract tests for this then merge in the exception modifications

> 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.
