> While scanning local indexes during regions merge we might end up with
> NegativeArraySizeException which leads to RS down. The reason for this is
> some times HBase won't do real seek and considered fake keyvalues(can be scan
> start row) as seeked kvs. In that case we ended up with this issue when we
> call peek without seek. So for local indexes we need to enforce seek all the
> time for scanning local index reference files.
