'RecordReader' is invalid becausa Controller Service is disabled ... Always getting this error while using ConvertRecord processor ?

[#1]

Hi @Haider Naveed

Have you confirmed that the Controller Services used by the processor (either the Record Reader or Record Reader) are enabled? You can navigate to them using the arrow icon that is next to each on the Properties Tab of ConvertRecord.

I wrote a tutorial on using Convert Record (https://community.hortonworks.com/articles/115311/convert-csv-to-json-avro-xml-using-convertrecord-p.html) where you might find some helpful info/screenshots.
