Generate incremental key in Hive

Generate incremental key in Hive

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
