[jira] [Created] (DRILL-2933) RecordBatchLoader.load(...) calls
catch SchemaChangeException that load(...) never throws
Daniel Barclay (Drill) created DRILL-2933:
---------------------------------------------
Summary: RecordBatchLoader.load(...) calls catch SchemaChangeException that load(...) never throws
Key: DRILL-2933
URL: https://issues.apache.org/jira/browse/DRILL-2933
Project: Apache Drill
Issue Type: Bug
Reporter: Daniel Barclay (Drill)
There are about 9 calls to RecordBatchLoader.load(...) that apparently try to detect schema changes by catching SchemaChangeException.
However, RecordBatchLoader.load(...) never actually throws SchemaChangeException to indicate a schema change--it returns true to indicate that.
Those 9 calls do not also check the return value, so they cannot detect schema changes.
(To find those calls, comment out the "throws SchemaChangeException" on RecordBatchLoader.load(...) and follow the Java compilation errors.)
