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 ...

Hi Madhura,   The following link may be usefull for your question https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.0.6.0/bk_installing_manually_book/content/rpm-chap1-11.html   For calculating  maximum number of containers allowed per node. The following formula can be used: # of containers = min (2*CORES, 1.8*DISKS, (Total available RAM) / MIN_CONTAINER_SIZE) Where MIN_CONTAINER_SIZE is the minimum container size (in RAM). This value is dependent on the amount of RAM available -- in smaller memory nodes, the minimum container size should also be smaller   Thanks AKR ... View more
