The issue is specific to the case when one of the key columns is of type
varchar. For this case, the internal logic that decodes the boundary values
expects the length to be at the beginning of the varchar. The boundary values
as read from hbase don't adhere to this condition. Changes are done in
NATable.cpp to update the boundary value to include the length so the decoding
logic can process it correctly.

> A compiler crash was observed in compiler rangePartitioning after an hbase
> partition split. The problem can be easily recreated on a workstation by
> forcing a partition split from the hbase master page.
> When a crash occurs the following stack trace is generated:
