--------------------------------------
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.
