Subject [jira] [Commented] (HDFS-8115) Make PermissionStatusFormat public
Date Thu, 09 Apr 2015 18:38:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8115?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14487931#comment-14487931

Haohui Mai commented on HDFS-8115:

The id of user / group only makes sense for a particular run of NN only.

This is an implementation detail and it should not be exposed to the public.

> implementations of {{INodeAttributeProvider}} are required to provide an implementation
of {{getPermissionLong()}} method. Unfortunately, the long permission format is an encoding
of the user, group and mode with each field converted to int using {{SerialNumberManager}}
which is package protected.
> Thus it would be nice to make the {{PermissionStatusFormat}} enum public (and also make
the {{toLong()}} static method public) so that user specified implementations of {{INodeAttributeProvider}}
may use it.
> This would also make it more consistent with {{AclStatusFormat}} which I guess has been
made public for the same reason.
