The UDTF seems to be forwarding the object as-is. From a quick look in the
UDTF, there's a convertIfNecessary in there - might need some analysis to
figure that out.

But looks like this is breaking the small data-size runs only. You can
lower the thresholds and try again.

set hive.fetch.task.conversion.threshold=-1;
