Subject [jira] [Commented] (HADOOP-14428) s3a: mkdir appears to be broken
Date Thu, 01 Jun 2017 22:58:04 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14428?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16033870#comment-16033870

Aaron Fabbri commented on HADOOP-14428:
---------------------------------------

Ok [~liuml07], I confirmed that your patch fixes the reproduction I mentioned (mkdir with
trailing slash).

One question on your patch:  I'm wondering why the existing test code did not catch this bug?
 It looks like you added new test cases that also use unqualified paths.  I would guess that
the trailing slash gets removed in S3AFileSystem in qualify(), but only when it is not absolute?
 So the existing test did not catch it?

My reproduction uses an absolute path though, so I'm confused.

Anyways, just curious.  I am still +1 on the patch assuming you get a clean Yetus run.

> Reproduction is:
> hadoop fs -mkdir s3a://my-bucket/dir/
> hadoop fs -ls s3a://my-bucket/dir/
> ls: `s3a://my-bucket/dir/': No such file or directory
> I believe this is a regression from HADOOP-14255.
