Merge Operation Fails -gpload utility greenplum

We would like try to describe my problem below: We have small gpdb cluster. In that,we are trying for Data integration using Talend tool.

We are trying to load the incremental from a table to another table, quite simple... I thought...

Job Data Flow is

         tgreenplumconnection
                  | 
tmssqlinput--->thdfsoutput-->tmap-->tgreenplumgpload--tgreenplumcommit
