Selvaganesan Govindarajan commented on TRAFODION-2254:
------------------------------------------------------

The phoneix test at tests/phx/src/test/java/org/trafodion/phoenix/end2end/SaltedTableUpsertSelectTest.java needs to be reverted back to use 'MERGE'. Remove the CQD traf_upsert_mode in this program
