Hi I am using "from pyspark import pandas as ps" in a master build yesterday.
I do have some columns that I need to join to one.
In pandas I use update.
54 FD_OBJECT_SUPPLIES_SERVICES_OBJECT_SUPPLY_SERVICE_ADDITIONAL_INFORMATION 23 non-null object
55 FD_OBJECT_SUPPLIES_SERVICES_OBJECT_SUPPLY_SERVICE_ADDITIONAL_INFORMATION.P 24348 non-null object
pd1['FD_OBJECT_SUPPLIES_SERVICES_OBJECT_SUPPLY_SERVICE_ADDITIONAL_INFORMATION'].update(pd1['FD_OBJECT_SUPPLIES_SERVICES_OBJECT_SUPPLY_SERVICE_ADDITIONAL_INFORMATION.P'])
---------------------------------------------------------------------------
