> HBase 2.0.0 removed PREFIX_TREE encoding so users need to modify data block encoding to something else before upgrading to HBase 2.0+. A tool would help users to verify that there are no tables left with PREFIX_TREE encoding.
> The tool needs to check the following:
> * There are no tables where DATA_BLOCK_ENCODING => 'PREFIX_TREE'
> * -Check existing hfiles that none of them have PREFIX_TREE encoding (in case table description is changed but hfiles were not rewritten)-
