HI, my company does not allow us to use non-managed service accounts (i.e. user knows the id/pwd) to access production systems. Instead they provide means to get the creds at run time by using an alias and calling a provider. I have a flow that queries Cassandra. I have the executescript running python getting the id/pwd from a supplied alias working fine and putting that in the downstream flowfile as an attribute. But the query cassandra processor will only allow a password from the variable registry. I do not know how to use the password obtained at runtime for this. Can you please provide your suggestions or guidance on how to proceed? Thank you.
