https://github.com/apache/spark/pull/18756
You mean we can provide the different type of values with different
default values? like int with 0 ,and string with "" ?Or we set the default
values when define the table? @gatorsmile @maropu I set the default to Null
,because the "insert into ..." sentence in hive handle in this way, and I want
to correspond with Hive.
