> Drill fails on Schema changes
> ------------------------------

> Key: DRILL-6223
> URL: https://issues.apache.org/jira/browse/DRILL-6223
> Project: Apache Drill
> Issue Type: Improvement
> Components: Execution - Relational Operators
> Affects Versions: 1.10.0, 1.12.0
> Reporter: salim achouche
> Assignee: salim achouche
> Priority: Major
>
> Drill Query Failing when selecting all columns from a Complex Nested Data
> File (Parquet) Set). There are differences in Schema among the files:
> * The Parquet files exhibit differences both at the first level and within
> nested data types
> * A select * will not cause an exception but using a limit clause will
> * Note also this issue seems to happen only when multiple Drillbit minor
> fragments are involved (concurrency higher than one)
