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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
