I am streaming messages from Eventhub. Part of the message body will contain the local directory path where to read in the file from. Therefore, my origin is eventhub streaming messages and a subsequent processor would need to be reading in a file from the path specified in the message. Is this possible? If so, how so?

I don't know if this is the best way, but you could use a Groovy Evaluator Processor to read the file. You'll need to grant the Groovy script permissions to read from disk.

Update sdc-security.policy with:

// groovy source code - allow to read a file from disk
grant codebase "file:///groovy/script" {
   permission java.util.PropertyPermission "*", "read";
   permission "/YOUR_PATH_HERE/*", "read";

You could also write your own Stage/Processor if you wanted.
