Custom Aggregations for the Group recipe with DSS engine

UserBird

Is it possible to use the "Custom aggregations" tab in the Group recipe when using the DSS recipe engine or does the engine need to be "in-database" for that tab to be useful? I've tried using it but I cannot reference columns in the input dataset (which is a file).

Thanks and I am using Data Science Studio 4.0.7.

Hi,

Custom aggregations are only possible in the SQL, Hive, Impala and Spark engines, so you'll need one of these to be available (either because the dataset is a SQL table, on HDFS, or if you have Spark installed)
