Hi,   This seems to be typeconversion issue in the timestamp field.  did you tried casting the timestamp into a string while populating spark data frame and then you can again convert that string into spark timestamp datatype? (i.e) after fetching the value from the Query the timestamp value needs to be converted into string in spark df and then reconvert that string to spark timestamp instead of directly pushing values from Netezza to spark because if you convert to string, it will not have datatype compatibility issues and this should work.   Thanks AKR ...
