### What changes were proposed in this pull request? In hive script transform serde mode, NULL format default is `\\N` ``` String nullString = tbl.getProperty( serdeConstants.SERIALIZATION_NULL_FORMAT, "\\N"); nullSequence = new Text(nullString); ``` I make a mistake that in Spark's code we need to fix and keep same with hive too. So add some test case to show this issue. ### Why are the changes needed? add UT ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested?
