------------------------------
Description:
We are trying to merge data using DeltaTable's merge API. on inserting a null
value into the not-null column results in NullPointerException instead of
throwing constrain violation error
^Caused by: java.lang.NullPointerExceptionCaused by:
java.lang.NullPointerException at

Please find the sample program [^NotNullIssue.scala] reading source data from
parquet files [^cdwqasourceupdate.7z] and writing data with merge to
[^cdwqatgtupdate.7z]
