My logic is, from column1 if value is TEST or MASTER print it as TEST or MASTER in o/p column1 and load the ID of TEST or MASTER from i/p column2 to o/p column2.
If column1 contains other then TEST or MASTER print it as NA in o/p column1 and load the ID of NA from i/p colummn2 to o/p column2.
The problem i'm facing is, i was able to get the proper o/p of ID for TEST or MASTER but for NA i'm getting null values.
In tmap variable i'm changing the values of column1 to TEST or MASTER or NA. And in expression editor i'm fetching the required values from i/p column2.
There are 20k records which contains TEST,MASTER,NA in my o/p column1, but only 10k records contains the ID which are TEST,MASTER in o/p column2 and rest is null which contains NA in o/p column2. Is there any way to get the ID of NA. Whether i need to change anything in expression editor.
My job design is thiveinput->tmap->thdfsoutput-thiveload
Input and output columns are string.
