Hi, in fact, the same problem happens when I try several joins together:
SELECT *
FROM sales INNER JOIN magasin ON sales.STO_KEY = magasin.STO_KEY
INNER JOIN eans ON (sales.BARC_KEY = eans.BARC_KEY and magasin.FORM_KEY =
eans.FORM_KEY)
py4j.protocol.Py4JJavaError: An error occurred while calling o1229.sql.
: java.lang.RuntimeException: [1.269] failure: ``UNION'' expected but
`INNER' found
SELECT sales.Date AS Date, sales.ID_FOYER AS ID_FOYER, Sales.STO_KEY AS
STO_KEY,sales.Quantite AS Quantite, sales.Prix AS Prix, sales.Total AS
Total, magasin.FORM_KEY AS FORM_KEY, eans.UB_KEY AS UB_KEY FROM sales INNER
JOIN magasin ON sales.STO_KEY = magasin.STO_KEY INNER JOIN eans ON
(sales.BARC_KEY = eans.BARC_KEY and magasin.FORM_KEY = eans.FORM_KEY)

I use spark 1.1.0, so I have an impression that sparksql doesn't support
several joins together.
