> ORC Delta encoding corrupts data when delta overflows long

> Key: HIVE-8078
> URL: https://issues.apache.org/jira/browse/HIVE-8078
> Project: Hive
> Issue Type: Bug
> Components: File Formats
> Affects Versions: 0.14.0, 0.13.1
> Reporter: Tim Patterson
> Assignee: Prasanth J
> Priority: Critical
> Attachments: HIVE-8078-testcase.patch, HIVE-8078.1.patch,

>
> There is an issue with the integer encoding that can cause corruption in
> certain cases.
> The following 3 longs cause this failure.
> 4513343538618202711
> 2911390882471569739
> -9181829309989854913
> I believe that even though the numbers are in decreasing order, the delta
> between the last two numbers overflows causing a positive delta, in this case
> the last digit ends up being corrupted (the delta is applied for the wrong
> sign resulting in -3442132998776557225 instead of -9181829309989854913.
