Date Fri, 17 Nov 2017 18:30:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16257357#comment-16257357

Steve Loughran commented on HADOOP-15050:
-----------------------------------------

The new builder API is still unstable. We need to mention that in the release notes of 2.9.0
& 3.0

> swift throws an exception in createNonRecursive(), so fails to work with the new {{FileSystem.createFile(path)}}
which uses that mode by default (because its the right thing to do :)
