> We currently have major versions 0 and 1. The HBase checksum patch introduces minor version
0 and 1. Then the columnar HFileBlock might introduce yet another disk format version. We
need a simple but elegant framework to test the compatibility of code with all these disk
format versions. We also want to do this without much code duplication in TestHFileBlockCompatibility.
