HBase translator - INSERT could rewrite the data

The HBase translator translates INSERT as UPSERT, which is an "alias" for both INSERT and UPDATE statement. It means, if user issues same INSERT statement twice, no exception is thrown [1]. I expect that [2] could rewrite the data.

Additional note: I was not able to verify my assumption because of https://issues.jboss.org/browse/TEIID-3619

[1]
INSERT INTO smalla (intkey) VALUES (55) is translated as UPSERT INTO smalla (intkey) VALUES (55)

[2]
INSERT INTO smalla (intkey, name) VALUES (1, 'name1')
INSERT INTO smalla (intkey, name) VALUES (1, 'name2')
