> ScanBatch is the Drill operator executor that handles most readers. Like most Drill operators,
it uses an ad-hoc set of error detection and reporting methods that evolved over Drill development.
> This ticket asks to standardize on error handling as outlined in DRILL-5083. This basically
means reporting all errors as a {{UserException}} rather than using the {{IterOutcome.STOP}}
return status or using the {{FragmentContext.fail()}} method.
> This work requires the new error codes introduced in DRILL-5511, and is a step toward
making readers aware of vector size limits.
