hive query with column masking failed with ParseException Table DDL {code:java} CREATE TABLE `emp`( `id` string, `name#` string); {code} The following query failed {code:java} select `emp`.`id`, `emp`.`name#` from (SELECT `id`, CAST(mask_show_first_n(name#, 4, 'x', 'x', 'x', -1, '1') AS string) AS `name#`, BLOCK__OFFSET__INSIDE__FILE, INPUT__FILE__NAME, ROW__ID FROM `default`.`emp` )`emp`; {code} Error: Error while compiling statement: FAILED: ParseException line 1:79 character '#' not supported here (state=42000,code=40000) quoting manually helped {code:java} select `emp`.`id`, `emp`.`name#` from (SELECT `id`, CAST(mask_show_first_n(`name#`, 4, 'x', 'x', 'x', -1, '1') AS string) AS `name#`, BLOCK__OFFSET__INSIDE__FILE, INPUT__FILE__NAME, ROW__ID FROM `default`.`emp` )`emp`; {code} manual query change will not work for Ranger authorizer as following query {code:java} select * from emp; {code} will be rewritten to {code:java} select `emp`.`id`, `emp`.`name#` from (SELECT `id`, CAST(mask_show_first_n(name#, 4, 'x', 'x', 'x', -1, '1') AS string) AS `name#`, BLOCK__OFFSET__INSIDE__FILE, INPUT__FILE__NAME, ROW__ID FROM `default`.`emp` )`emp`; {code} Ranger apply the transformer for column here so we should consider the enclosing the column names in the back-ticks to make it work https://github.com/apache/ranger/blob/master/hive-agent/src/main/java/org/apache/ranger/authorization/hive/authorizer/RangerHiveAuthorizer.java#L1332 I have opened https://issues.apache.org/jira/browse/RANGER-3009 for Ranger but checking we hive can pass the column name enclosed in back-ticks while passing the priv-object to ranger https://github.com/apache/hive/blob/7dd12cd9d77aaaa20f22159062d3c3e5d7bdd127/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzer.java#L11977 -- This message was sent by Atlassian Jira (v8.3.4#803005)
