Github user vinodkc commented on the issue: https://github.com/apache/spark/pull/22171 @gatorsmile @HyukjinKwon @viirya , I rechecked the customer scenario. It seems dataframe is saved as csv file and then netezza loads the csv data into netezza table. In csv output 0 values, with higher scale than 6, are store in scientific notation and due to this [limitation](http://www-01.ibm.com/support/docview.wss?crawler=1&uid=swg21570795) of netezza ,it fails to load the data. if the 0 values in csv is in non scientific notation, netezza loads the data.
