Scott commented on NIFI-972:
----------------------------
I like the rows.count idea, I think that is the best solution, relatively quick
to implement too!

> Jonathan Lyons reported:
> Just getting started with NiFi here. I am attempting to run a static query
> in MySQL using the ExecuteSQL processor. It is set to run on a 5 second
> interval. Since ExecuteSQL appears to need an input flow file I'm using a
> GenerateFlowFile processor to produce a random file every 5 seconds.
> Unfortunately, I'm getting a very vague ArrayIndexOutOfBounds exception
> when I hit play on the flow:
> java.lang.ArrayIndexOutOfBoundsException: 8
> at org.apache.avro.generic.GenericData$Record.put(GenericData.java:129)
> at org.apache.nifi.processors.standard.util.JdbcCommon.convertToAvroStream
> at
> org.apache.nifi.processors.standard.ExecuteSQL$1.process(ExecuteSQL.java:141)
> It’s seem to be bug in createSchema() which creates Arvo schema.
> When createSchema() will encounter unknown type, no Arvo column info will be
> created. And Arvo schema has less columns than ResultSet row…
