> Negative values corruption for RLE-encoded INT32 columns
> --------------------------------------------------------
>
> Key: KUDU-1437
> URL: https://issues.apache.org/jira/browse/KUDU-1437
> Project: Kudu
> Issue Type: Bug
> Components: cfile
> Affects Versions: 0.6.0, 0.7.0, 0.8.0
> Reporter: Przemyslaw Maciolek
> Assignee: Todd Lipcon
> Priority: Blocker
>
> Putting a sequence of negative values to INT32 RLE-encoded column corrupts
> the data after compaction.
> The exact recipe to reproduce it is following:
> 1) Put a sequence of negative values in descending order to an INT32
> RLE-encoded column (it's a primary key in my case, but maybe regular columns
> are affected as well)
> 2) Wait for compaction
> 3) See you data converted to -1's
> A Gist showing an example of data corruption is available here:
> https://gist.github.com/pmaciolek/dfc6a95ff85145d23774cb5d1a9f5a4f (based on
> {{sample.cc}} provided with Kudu sources, note that {{-std=c++11}} might need
> to be added to the compiler flags)
