> Similar to  KUDU-2049, the binary prefix block encoder has a bug when seeking 
> past the end of the block (i.e to the offset past the last element). The bug 
> only causes issues in very specific circumstances:
> - the number of elements in the block has to be a multiple of 16 (the 
> "restart interval")
> -- this causes the code to interpret the "restart count" at the end of the 
> block data as an offset instead of part of the footer.
> - this value, when interpreted as an offset, points to a piece of data in the 
> block which, when interpreted as a varint, ends up large enough to point past 
> the end of the block.
> This results in an error like:
> F0730 09:56:07.291882 124055 binary_prefix_block.cc:325] Check failed: 
> _s.ok() Bad status: Corruption: Could not decode value length data at idx 32
