------------------------------------------
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.
