----------------------------------------
Summary: Use custom Tez input initializer to support schema
evolution
Key: HIVE-7071
URL: https://issues.apache.org/jira/browse/HIVE-7071
Project: Hive
Issue Type: Bug
Reporter: Gunther Hagleitner
Assignee: Gunther Hagleitner
Attachments: HIVE-7071.1.patch
Right now we're falling back to combinehivefileinputformat and switch of am
side grouping when there's different schemata in a single vertex. We need to
handle this in a custom initializer so we can still group on the AM.
