             Summary: Impala should check file schema as well to check full ACIDv2 files
                 Key: IMPALA-10115
                 URL: https://issues.apache.org/jira/browse/IMPALA-10115
             Project: IMPALA
          Issue Type: Bug
            Reporter: Zoltán Borók-Nagy


Currently Impala checks file metadata 'hive.acid.version' to decide the full ACID schema.

There are cases when Hive forgets to set this value for full ACID files, e.g. major query-based compactions.

So if 'hive.acid.version' is not present, Impala should still look at the schema elements to be sure about the file format.
