Hi,
I am trying to transform data from Raw to timeseries in CDF. I made a query and everything seems ok, but when I use distinct to check the external id uniqueness, I get error message:
"Cannot have map type columns in DataFrame which calls set operations(intersect, except, etc.), but the type of column metadata is map<string,string>;
I don’t know why I get this message, Isn’t it possible to use distinct when wi do MAP or To_Metadata mapping?
