> Key: IMPALA-10554
> URL: https://issues.apache.org/jira/browse/IMPALA-10554
> Project: IMPALA
> Issue Type: Bug
> Components: Security
> Affects Versions: Impala 3.4.0
> Reporter: Quanlong Huang
> Priority: Critical
> Attachments: column_masking_policy.png
>
>
> Per RANGER-1087 and RANGER-1100, table modifications(insert/delete/update)
> should be blocked when row-filter/column-masking policy is enabled for the
> user.
> Currently, Impala doesn't block them, which is a bug considering to Hive's
> behavior.
> *Reproducing the issue*
> Create a table and a column masking policy on it:
> {code:sql}
> hive> create table hql_tbl (id int, name string) stored as textfile;
> hive> insert into table hql_tbl values (0, 'aaa'), (1, 'bbb'), (2, 'ccc');
> {code}
> Column masking policy:
> !column_masking_policy.png|width=534,height=572!
> In Hive, the INSERT will be denied:
> {code:sql}
> hive> insert into table hql_tbl values (3, 'ddd');
> Error while compiling statement: FAILED: HiveAccessControlException
> Permission denied: user [admin] does not have [UPDATE] privilege on
> [default/hql_tbl]
> {code}
> However, the user is able to insert values using Impala.
> The related Ranger config is
> xasecure.hive.block.update.if.rowfilter.columnmask.specified.
