-------------------------------------
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?

> When saving Double.NaN via prepared statement into column of type Double

> Statement stmt = phoenixConnection.createStatement();
> stmt.executeUpdate(sql);
> phoenixConnection.commit();

> sql = "UPSERT INTO test25 (id, col1,col2) VALUES (?,?,?)";
> PreparedStatement ps = phoenixConnection.prepareStatement(sql);
> ps.setInt(1, 12);
