Owen O'Malley commented on HIVE-14007:
--------------------------------------
Ok, I've updated the pull request https://github.com/apache/hive/pull/81 and
will post a new patch once ORC 1.2.3 is released.
The patch ensures that the moved config variables don't create an error by
adding them to the exception map.
https://github.com/omalley/hive/commit/d078aea84ecb1fe7d3e9b95cc845dfbdee63587c#diff-7f16e0de4170e5b6c031990da80f5643
As to why the patch is changing test files, it is because the ORC project has a
couple of fixes and features that hadn't been back ported to Hive.
In particular,
* ORC-101 fixes the bloom filters to use utf-8 rather than the jvm default
encoding. This changes the size of the ORC files and their write version. There
is an option to write the old broken bloom filters in addition to the new ones.
* ORC-54 makes the default for schema evolution to be by name instead of
position if the ORC files has real column names. Some of the tests required the
old behavior and so I changed the names to match for the intended matches. Note
that Hive 1.x never got the fix to encode the real column names in the file
metadata, so all files written by Hive 1.x will use positional matching.
