[jira] [Created] (PARQUET-162) ParquetThrift should throw when unrecognized columns are passed to the column projection API

Alex Levenson created PARQUET-162:
-------------------------------------

             Summary: ParquetThrift should throw when unrecognized columns are passed to the column projection API
                 Key: PARQUET-162
                 URL: https://issues.apache.org/jira/browse/PARQUET-162
             Project: Parquet
          Issue Type: Bug
          Components: parquet-mr
            Reporter: Alex Levenson


It appears that giving wrong / unrecognized column names to the projection API doesn't fail fast or even report that the columns were unrecognized at all.

We should also log at start up what columns are being projected, this is useful info to have in the logs.
