Subject [jira] [Commented] (HDFS-12170) Ozone: OzoneFileSystem: KSM should maintain key creation time and modification time
Date Tue, 25 Jul 2017 03:22:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16099433#comment-16099433
] 

Yiqun Lin commented on HDFS-12170:
----------------------------------

Thanks [~msingh] for the work on this! The patch also looks good to me. One comment: seems
the modify time is absolutely same with the created time now. Is there any case that we just
update the modify time in future under OzoneFileSystem? Just curious for this.
Hi [~vagarychen],
bq. Is there a particular reason for this? can we just use one type?
Here some other places used {{String}} type, I think the reason is that the field {{createdOn}},
{{modifiedOn}} is the date string rather than a long type number value.
