Deleting files with Apache Nifi


I'm curious about how a flow would look.

So I have written a spark program to determine missing data between my source(Oracle,keeps deleting files) and my destination(IBM DB2). 
I bring in the data into my nifi flow with GETHDFS and it brings in the primary keys of the data that is missing, I want to then use these primary keys to run a process that will delete them from destination(IBM Db2). 

Any help would be appreciated.
