Sean Owen resolved SPARK-12679.
-------------------------------
    Resolution: Invalid

I can't make out what you're describing here. For example, the result is correct if there are no rows in the table.

> Hi,
> I don't know where to put my fingre on that issue, on the connector or on Spark, but sometimes when I do SQL query I get empty rows.
> Example code:
>      rows = Arrays.asList(sparkCtx.sparkSql(“select * from tmpTable”).collect());
>       iterate Row row -> rows
> system-out(row.getString(0)) -----return null
> I tried to find open bugs on the collect method, without any luck.
