[jira] [Created] (HBASE-20592) Create a tool to verify tables do not have prefix tree encoding

Peter Somogyi created HBASE-20592:
-------------------------------------

             Summary: Create a tool to verify tables do not have prefix tree encoding
                 Key: HBASE-20592
                 URL: https://issues.apache.org/jira/browse/HBASE-20592
             Project: HBase
          Issue Type: New Feature
          Components: Operability, tooling
            Reporter: Peter Somogyi
            Assignee: Peter Somogyi
             Fix For: 2.1.0


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)
