(was: Hi, I have done the unit test. But, come to a problem.

If I write Null into the table (Double Type Column) , it would be fine for writing. However, after the cell is filled, I read the row by HadoopAPI and it will get 0.0 as default value.

test data:  val dataset = Seq((1, 123.0, "String1"), (2, Double.NaN, "String2"), (3, Float.NaN, "String3"), (4, 456, null))
and here is the sql query result:
id: 1 double value: 123.0 string value: String1
id: 2 double value: 0.0 string value: String2
id: 3 double value: 0.0 string value: String3
id: 4 double value: 456.0 string value: null

Any suggestion? Or It is already the optimal solution?)
