Description

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

 

        boolean grantOption = MetastoreDirectSqlUtils.extractSqlBoolean(privLine[grantOptionIndex]);

MetastoreDirectSqlUtils::extractSqlBoolean should handle integers to support directSQL in postgres.
