-------------------------------------
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)
