Hi @dadasami,
Sorry, I don’t exactly know what’s the problem with EmrEtlRunner here, it always has been a cryptic piece of software. But while this is not exactly what you’re asking - can I recommend you to have a look at new RDB Loader R35 that is not depending on EmrEtlRunner (which is going to be deprecated very soon), has much cleaner configuration and integration with fargate (we provide official docker image). Let me know if you need any help with setup - I’m very keen to polish the documentation if there are any issues.
