Subject [jira] [Commented] (HADOOP-14581) Restrict setOwner to list of user when security is enabled in wasb
Date Wed, 12 Jul 2017 10:10:01 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16083750#comment-16083750

Steve Loughran commented on HADOOP-14581:

(Had to add a second patch to get branch-2 to compile; java 7 doesn't like us using non-final
variables in inner classes/closures. My fault for not testing the branch-2 build before committing

> Currently in azure FS, setOwner api is exposed to all the users accessing the file system.
> When Authorization is enabled, access to some files/folders is given to particular users
based on whether the user is the owner of the file.
> So setOwner has to be restricted to limited set of users to prevent users from exploiting
owner based authorization of files and folders.
> Introducing a new config called fs.azure.chown.allowed.userlist which is a comma seperated
list of users who are allowed to perform chown operation when authorization is enabled.
