             Summary: Select query on table with remote database returns NULL 
values with postgreSQL and Redshift data connectors
                 Key: HIVE-27316
                 URL: https://issues.apache.org/jira/browse/HIVE-27316
             Project: Hive
          Issue Type: Bug
            Reporter: Venugopal Reddy K


*Brief Description:*

Few datatypes are not mapped from postgres/redshift to hive data types. Thus 
values for unmapped columns are shown as null.

 

*Steps to reproduce:*

1. create connectors for postgres,redshift, and create remote database with the 
respective connectors.

 
{code:java}
create connector rscon1 type 'postgres' url 
'jdbc:redshift://redshift.us-east-2.redshift.amazonaws.com:5439/dev?ssl=false&tcpKeepAlive=true'
 WITH DCPROPERTIES 
('hive.sql.dbcp.username'='cloudera','hive.sql.dbcp.password'='Cloudera#123','hive.sql.jdbc.driver'='com.amazon.redshift.jdbc.Driver','hive.sql.schema'
 = 'public');

create REMOTE database localdev1 using rscon1 with 
DBPROPERTIES("connector.remoteDbName"="dev");

create connector pscon1 type 'postgres' url 
'jdbc:postgresql://postgre.us-east-2.rds.amazonaws.com:5432/postgres?ssl=false&tcpKeepAlive=true'
 WITH DCPROPERTIES 
('hive.sql.dbcp.username'='postgres','hive.sql.dbcp.password'='Cloudera#123','hive.sql.jdbc.driver'='org.postgresql.Driver','hive.sql.schema'
 = 'public');

create REMOTE database localdevps1 using pscon1 with 
DBPROPERTIES("connector.remoteDbName"="postgres");
{code}
2. Execute select query on table(in remote db) having int2, int4, float4, 
float8, bool, character(n) columns shows NULL values.
