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

             Summary: NPE trying to move results of a subselect into an RDBMS 
using HPL/SQL
                 Key: HIVE-14416
                 URL: https://issues.apache.org/jira/browse/HIVE-14416
             Project: Hive
          Issue Type: Bug
          Components: hpl/sql
    Affects Versions: 2.1.0
            Reporter: Carter Shanklin


I was trying to use HPL/SQL to move some records from Hive to Postgres using 
this script:

{code}
MAP OBJECT remote TO pgtable AT mydbconn;
insert into remote values ( select * from hivetable );
{code}

When I run this script I get this NPE:
{code}
Open connection: jdbc:hive2://hdp250.example.com:10000 (285 ms)
Starting query
Query executed successfully (127 ms)
Exception in thread "main" java.lang.NullPointerException
