Jason Lowe commented on YARN-6820:
----------------------------------
Oh sorry, I missed that branch. I noticed there's both a YARN-5355-branch-2
_and_ YARN-5355_branch2, but I don't see a YARN-5355_branch_2. Both branches
have commits from August but are not the same, so it's not clear to me which
one is "correct." Seems like one of them should be deleted to remove any
confusion.

> Need to provide a way to restrict read access in ATSv2. Not all users should
> be able to read all entities. On the flip side, some folks may not need any
> read restrictions, so we need to provide a way to disable this access
> restriction as well.
> Initially this access restriction could be done in a simple way via a
> whitelist of users allowed to read data. That set of users can read all data,
> no other user can read any data. Can be turned off for all users to read all
> data.
> Could be stored in a "domain" table in hbase perhaps. Or a configuration
> setting for the cluster. Or something else that's simple enough. ATSv1 has a
> concept of domain for isolating users for reading. Would be good to keep that
> in consideration.
> In ATSv1, domain offers a namespace for Timeline server allowing users to
> host multiple entities, isolating them from other users and applications. A
> “Domain” in ATSV1 primarily stores owner info, read and& write ACL
> information, created and modified time stamp information. Each Domain is
> identified by an ID which must be unique across all users in the YARN cluster.
