---------------------------------------

             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.
