------------------------------------
Summary: Difference in required privileges to execute a UDF in a
SELECT query between Impala and Hive
Key: IMPALA-11769
URL: https://issues.apache.org/jira/browse/IMPALA-11769
Project: IMPALA
Issue Type: Task
Reporter: Fang-Yu Rao
Assignee: Fang-Yu Rao
After IMPALA-10986, to execute a UDF of a database in a SELECT query, a user is
required to additionally have the SELECT privilege on the UDF beside any of
INSERT, REFRESH, SELECT on the database. The requirement is a bit different
from that in Hive when Ranger is the authorization provider in that Hive's
Ranger plugin *only* requires the user to have the SELECT privilege on the UDF.
We should decide whether we would like to change Impala's behavior with respect
to UDF execution in a SELECT query so that Impala and Hive would have the same
required privilege.
