-----------------------------------------
Summary: Case-sensitivity for column names when reading from ORC
Key: HIVE-20693
URL: https://issues.apache.org/jira/browse/HIVE-20693
Project: Hive
Issue Type: Bug
Components: Hive, ORC
Affects Versions: 2.3.2
Reporter: Alexandre Crayssac
Hello everyone,
I observed a different behavior between version 1.2.1 and 2.3.2 (that's the
only two versions I've been able to test).
When creating an external table pointing to ORC files and having upper cased
column names in the ORC files metadata I'm able to read the data on 1.2.1 but
not on 2.3.2.
I tested with both upper cased and lower cased column names in my CREATE TABLE
statement and it does not work in both cases. Looks like normal since column
names are normalized to lower case in Hive.
So, I would like to know if this is a feature or a bug in Hive 2.3.2 ?
In fact, if this is a feature it would be impossible to have upper case column
names in ORC files with Hive 2.3.2.
Please, let me know if you need more informations.
Kind regards,
Alexandre
