Using QueryDatabaseTable processor in MiNiFi

I have a small flow that was exported from NiFi and it uses a
QueryDatabaseTable processor. When the flow is converted to yaml and set in
MiNiFi I get the following error in MiNiFi's app log:

ERROR [main] o.apache.nifi.controller.FlowController Could not create
Processor of type org.apache.nifi.processors.standard.QueryDatabaseTable
for ID 9570c06a-837b-3ac0-0000-000000000000; creating "Ghost" implementation

at org.apache.nifi.minifi.MiNiFi.main(MiNiFi.java:239)

I verified in the log that the QueryDatabaseTable processor is being loaded
during MiNiFi's start up. Just above this message I can see that the DBCP
controller service seems to be ok:

2017-07-27 09:32:54,877 INFO [main]
o.a.n.c.s.StandardControllerServiceProvider Created Controller Service of
type org.apache.nifi.dbcp.DBCPConnectionPool with identifier

Did I forget to do something?

Thanks,
Jeff

Okay, thanks for the update.  Figuring out where things went awry would be
helpful to make that process easier.  We certainly have a lot of room to
improve on our documentation.

I went through the steps again and it worked fine so it was total user
failure somewhere on my part. I am curious as to where I went wrong so I am
trying to reproduce it to see if it's worth any documentation updates.

Thanks,
Jeff

Hey Jeff,

Could you please provide a full nifi-app.log of the startup?

Thanks,
Aldrin
