Subject [jira] [Commented] (HADOOP-12667) s3a: Support createNonRecursive API
Date Tue, 22 Dec 2015 20:05:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12667?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15068649#comment-15068649

Steve Loughran commented on HADOOP-12667:

hadoop already has some atomicity problems with create-no-overwrite, given the write doesn't
even happen until the close() call. But...createNonRecursive is potentially useful, as it
will fail-fast if the parent doesn't exist.

Looking at the patch, I can see we need the filesystem spec updated with coverage of the reinstated
method, ideally with a recommended IOE subclass {{FileNotFoundException}} if the parent isn't
there...then we can add this test here to the contract tests and roll it out across all the

Sean: fancy taking that on?
