How do i combine rows from same data source after they are splitup?

Anonymous — Tue, 18 Apr 2017 21:27:25 GMT

I want to combine output of tMap2,tMap4,tMap5 , so that I can write the final output in 1 file. Each of tMap components has comumns A,B,C. I want to combine them by tMap2.A=tMap4.A=tMap5.A && tMap2.B=tMap4.B=tMap5.B and want to keep C of each of the three tMap components.

Any help on how to do this , much appreciated..!

You cannot combine data flows issued from the same source in the subjob where they have been splitted.
Connect each flow to a tHashOutput, then start a new subjob (onSubjobOk) and merge or join the different flows (tHashInput) using a tUnit or a tMap.
