> Create utility to fix acid key index issue from HIVE-18817

> Key: HIVE-18907
> URL: https://issues.apache.org/jira/browse/HIVE-18907
> Project: Hive
> Issue Type: Bug
> Reporter: Jason Dere
> Assignee: Jason Dere
> Priority: Major
> Attachments: HIVE-18907.1.patch
>
>
> While HIVE-18817 will create new ORC Acid files from hitting the
> ArrayIndexOutOfBounds issue, existing files created before HIVE-18817 will
> still cause this issue. If there are delta directories then one way to
> generate new files is to perform a major compaction. But this does not work
> if there are no delta directories for the table/partition.
> Add a tool to fix the Acid ORC files directly in the case that a compaction
> cannot be performed.
