---------------------------------------
Summary: Direct SQL to fetch column privileges in refreshPrivileges may be broken in postgres
Key: HIVE-25077
URL: https://issues.apache.org/jira/browse/HIVE-25077
Project: Hive
Issue Type: Improvement
Reporter: Rajesh Balamohan
HIVE-22512 tried to fix direct-sql for col privileges.
However, "GRANT_OPTION" field in "TBL_COL_PRIVS" is marked as smallint in postgres. In code, it is retrieved as boolean.
Ref: [https://github.com/apache/hive/blob/master/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/MetaStoreDirectSql.java#L1533]
{code:java}
boolean grantOption = MetastoreDirectSqlUtils.extractSqlBoolean(privLine[grantOptionIndex]);
{code}
[https://github.com/apache/hive/blob/048336bd0c21163920557a60c88135b1d5b42d3d/standalone-metastore/metastore-server/src/main/java/org/apache/hadoop/hive/metastore/MetastoreDirectSqlUtils.java#L530]
MetastoreDirectSqlUtils::extractSqlBoolean should handle integers to support directSQL in postgres.
