Tim Armstrong created IMPALA-7087:
-------------------------------------
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.
