Generate incremental key in Hive

Anonymous — Tue, 15 Jan 2019 13:49:55 GMT

Hello,

I am using the tELTHiveInput, tELTHiveMap and tELTHiveOutput to read data from a Hive table and write it to a separate table. This works fine. However, I am now trying to generate a key for the target table, i.e. an incremental ID.

Is this possible to do? I found that you can generate a sequence such as this with tRowGenerator and use the expression Numeric.sequence(...) but I cannot actually connect it to tELTHiveMap to add it to the other columns. Any ideas?

Thank you,

Axel
