Aihua Xu commented on HIVE-13251: --------------------------------- [~jarcec] FYI. Seems we need to handle such backward compatibility although the file format/schema is incorrect to avro since some customers generated such files and see such issues after upgrading. > hive can't read the decimal in AVRO file generated from previous version > ------------------------------------------------------------------------ > > Key: HIVE-13251 > URL: https://issues.apache.org/jira/browse/HIVE-13251 > Project: Hive > Issue Type: Bug > Components: Hive > Affects Versions: 2.1.0 > Reporter: Aihua Xu > Assignee: Aihua Xu > > HIVE-7174 makes the avro schema change to match avro definition, while it > breaks the compatibility if the file is generated from the previous Hive. We > should allow to read old file format "precision" : "4", "scale": "8", but > write in the new format. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
