Create a tool to verify tables do not have prefix tree encoding

    XMLWordPrintableJSON

Details

    • PreUpgradeValidator tool with DataBlockEncoding validator was added to verify cluster is upgradable to HBase 2.

    Description

      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)
