-------------------------------------

             Summary: Impala is unable to read Parquet decimal columns with lower precision/scale than table metadata
                 Key: IMPALA-7087
                 URL: https://issues.apache.org/jira/browse/IMPALA-7087
             Project: IMPALA
          Issue Type: Sub-task
          Components: Backend
            Reporter: Tim Armstrong


This is similar to IMPALA-2515, except relates to a different precision/scale in the file metadata rather than just a mismatch in the bytes used to store the data. In a lot of cases we should be able to convert the decimal type on the fly to the higher-precision type.
