Subject [jira] [Commented] (HADOOP-13946) Document how HDFS updates timestamps in the FS spec; compare with object stores
Date Wed, 04 Jan 2017 15:55:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15798565#comment-15798565

Steve Loughran commented on HADOOP-13946:
-----------------------------------------

I think I've written this badly. I Had in my head write == the create() call, but from the
S3 protocol, it's when the PUT request began. Does this hold for multipart too?

> SPARK-17159 shows that the behavior of when HDFS updates timestamps isn't well documented.
Document these in the FS spec.
> I'm not going to add tests for this, as it is so very dependent on FS implementations,
as in "POSIX filesystems may behave differently from HDFS". If someone knows what happens
there, their contribution is welcome.
