> Project: Apache Drill
> Issue Type: Bug
> Components: Execution - Relational Operators

> HashJoin currently does not allow schema change in either build side or probe side. When HashJoin hit SchemaChangeException in the middle of execution, Drill reports a brief error message about SchemaChangeException, without providing any information what schemas are in the incoming batches. That makes hard to analyze the error, and understand what's going on.
> It probably makes sense to put the two differing schemas in the error message, so that user could get better idea about the schema change.
> Before Drill can provide support for schema change in HashJoin, the detailed error message would help user debug error.
