[jira] [Created] (IMPALA-9223) Don't require privileges on
unmaterialized columns
Quanlong Huang created IMPALA-9223:
--------------------------------------
Summary: Don't require privileges on unmaterialized columns
Key: IMPALA-9223
URL: https://issues.apache.org/jira/browse/IMPALA-9223
Project: IMPALA
Issue Type: Bug
Components: Security
Reporter: Quanlong Huang
Impala requires user privileges on all columns in the query, no matter whether those columns are materialized. This is a different behavior than Hive's.
For instance, for query "{{select id from (select * from customer_tiny) t}}", only the {{id}} column is materialized. Hive only requires SELECT privilege on the {{id}} column. However, Impala requires SELECT privileges on the table or all columns of the table.
We should consider taking the same behavior of Hive.
