Subject [jira] [Commented] (HADOOP-13222) s3a.mkdirs() to delete empty fake parent directories
Date Wed, 14 Sep 2016 13:43:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13222?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15490473#comment-15490473
] 

Steve Loughran commented on HADOOP-13222:
-----------------------------------------

if you create the object /aa/bb/ with the aws SDK, that's taken as a directory. create one
/aa/bb then that's viewed as a file: listings will stop at that point, and if you try to create
/aa/bb/cc then you'll get an error, because you can't have a file or directory under a file.
If the hadoop fs shell let you do that: it's a bug in the shell
