--------------------------------------
Hi [~thejas], would you review the latest patch?
> SQLStdAuthorizer expects external table creator to be owner of directory,
> does not respect rwx group permission. Only one user could ever create an
> external table definition to dir!

> Key: HIVE-12408
> URL: https://issues.apache.org/jira/browse/HIVE-12408
> Project: Hive
> Issue Type: Bug
> Components: Authorization, Security, SQLStandardAuthorization
> Affects Versions: 0.14.0
> Environment: HDP 2.2 + Kerberos
> Reporter: Hari Sekhon
> Assignee: Akira Ajisaka
> Priority: Critical

> When trying to create an external table via beeline in Hive using the
> SQLStdAuthorizer it expects the table creator to be the owner of the
> directory path and ignores the group rwx permission that is granted to the
> user.
> {code}Error: Error while compiling statement: FAILED:
> HiveAccessControlException Permission denied: Principal [name=hari,
> type=USER] does not have following privileges for operation CREATETABLE
> [[INSERT, DELETE, OBJECT OWNERSHIP] on Object [type=DFS_URI,
> name=/etl/path/to/hdfs/dir]] (state=42000,code=40000){code}
> All it should be checking is read access to that directory.
> The directory owner requirement breaks the ability of more than one user to
> create external table definitions to a given location. For example this is a
> flume landing directory with json data, and the /etl tree is owned by the
> flume user. Even chowning the tree to another user would still break access
> to other users who are able to read the directory in hdfs but would still
> unable to create external tables on top of it.
> This looks like a remnant of the owner only access model in SQLStdAuth and is
> a separate issue to HIVE-11864 / HIVE-12324.
