Review comment:
Unfortunetely, this DrillRuntimeException is created with data from inner
class (ColumnChunkIncPageReader) and there is no way to extract it at the
moment.

> Convert IndexOutOfBounds exception to UserException with context data where

>
> Key: DRILL-6724
> URL: https://issues.apache.org/jira/browse/DRILL-6724
> Project: Apache Drill
> Issue Type: Improvement
> Affects Versions: 1.14.0
> Reporter: Bohdan Kazydub
> Assignee: Bohdan Kazydub
> Priority: Major
> Fix For: 1.15.0
>
>
> Sometimes when IndexOutOfBoundsException is exposed to users it is not clear
> what causes the problem. Instead this exception may be converted to a more
> useful UserException containing context data like filename, line, position
> etc (depending on what is available from a reader for a given type).
> A possible approach is to add a method to a RecordReader interface which
> produces UserException of type ErrorType.DATA_READ with context data, so that
> when such an UserException is needed it can be easily obtained by invoking
> the method.
