> 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.
