Subject [jira] [Created] (DRILL-2933) RecordBatchLoader.load(...) calls catch SchemaChangeException that load(...) never throws
Date Fri, 01 May 2015 03:59:06 GMT
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.)
