["1427357147@qq.com" <14...@qq.com>]

HI  all,

I want to filter the data by the datatime.
In mysql, the colume is the DATETIME type, named A. 
I write my code like:
import java.util.Date;
newX.filter(newX.col("A").isNull().or(newX.col("A").lt(new Date()))).show();

I got error :
Exception in thread "main" java.lang.RuntimeException: Unsupported literal type class java.util.Date Wed Apr 11 16:17:31 CST 2018

How should I do to filter the datetime in dataset filter please?
