Description

Steps to reproduce are as follows:

1. Create a table with multiple column families

CREATE TABLE TBL (
  COL1 VARCHAR NOT NULL,
  COL2 VARCHAR NOT NULL,
  COL3 VARCHAR,
  FAM.COL4 VARCHAR,
  CONSTRAINT TRADE_EVENT_PK PRIMARY KEY (COL1, COL2)
)

2. Upsert a row

UPSERT INTO TBL (COL1, COL2) values ('AAA', 'BBB')

3. Query with DESC for the table

SELECT * FROM TBL WHERE COL2 = 'BBB' ORDER BY COL1 DESC

By following the above steps, we face the following exception.
