Gregory Chanan commented on HBASE-5317:
---------------------------------------

@Ted:
FSUtils.getTableDirs() excludes a specific list of directories.  Specifically:
{code}
     Arrays.asList(new String[]{ HREGION_LOGDIR_NAME, HREGION_OLDLOGDIR_NAME,
          CORRUPT_DIR_NAME, Bytes.toString(META_TABLE_NAME),
          Bytes.toString(ROOT_TABLE_NAME), SPLIT_LOGDIR_NAME }));
{code}

So if the MiniMRCluster creates a "target" directory, it will be returned.
