org.apache.hadoop.hbase.migration.NamespaceUpgrade
Upgrades old 0.94 filesystem layout to namespace layout Does the following: - creates system namespace directory and move .META. table there renaming .META. table to hbase:meta, this in turn would require to re-encode the region directory name
The pre-0.96 paths and dir names are hardcoded in here.

    doFsCommand(shell, new String [] {"-lsr", "/"});


    //upgrade to namespace as well
    Configuration toolConf = TEST_UTIL.getConfiguration();
    conf.set(HConstants.HBASE_DIR, TEST_UTIL.getDefaultRootDirPath().toString());
    ToolRunner.run(toolConf, new NamespaceUpgrade(), new String[]{"--upgrade"});


    TEST_UTIL.startMiniHBaseCluster(1, 1);
    // Assert we are running against the copied-up filesystem.  The copied-up
    // rootdir should have had a table named 'TestTable' in it.  Assert it
    // present.
