Sean Busbey commented on HBASE-20592:
-------------------------------------
Can we output anything else about the incompatible Data Blcok Encodings? and ID
number or something?
Can we provide a link to upgrade guidance in the ref guide that explains how
one goes about converting?
Please add a short name for the tool so that we don't need to tell people to
use a fully qualified class name.
> Create a tool to verify tables do not have prefix tree encoding

> 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)-
