Description

When running the following command:

 

/usr/hdp/2.6.3.0-235/hive2/bin/hplsql -e "
MAP OBJECT dep TO <SCHEMA>.<TABLE> AT lptdwhconn;
MAP OBJECT T TO <hive_table> AT hiveconn;
INSERT INTO T (cd_department,lb_departement,cd_region,lb_region)
SELECT d.cd_departement, d.lb_departement,d.lb_departement, d.cd_region, d.lb_region FROM dep d WHERE rownum < 2;"

 

I get an Exception :

 

Caused by: org.apache.hadoop.hive.ql.parse.SemanticException: Line 1:124 Table not found '<TABLE>'

If i run a smilar command :

/usr/hdp/2.6.3.0-235/hive2/bin/hplsql -e "
MAP OBJECT dep TO <SCHEMA>.<TABLE> AT lptdwhconn;
MAP OBJECT T TO <hive_table> AT hiveconn;

INSERT INTO T (cd_department,lb_departement,cd_region,lb_region)
SELECT 'a' as c1, 'b' as c2, 'c' as c3, 'd' as c4;"

everything works fine !Running two select statements on each table using the same MAP OBJECT Statements works also fine.

It seems that running INSERT INTO .... SELECT statement  using two tables from different connections failed.

Somehow, the MAP OBJECT does not seem to use the correct connection to find the table in this case.
