-----------------------------------------
Summary: 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: tserver
Affects Versions: 0.8.0, 0.7.0, 0.6.0
Reporter: Przemyslaw Maciolek
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)
