示例1: SchemaConfigured

 * Initialize table and column family name from an HFile path. If
 * configuration is null,
 * {@link SchemaMetrics#configureGlobally(Configuration)} should have been
 * called already.
 */

  this(conf);

  if (path != null) {
    String splits[] = path.toString().split("/");
    int numPathLevels = splits.length;

      // This path starts with an '/'.
      --numPathLevels;
    }
    if (numPathLevels < HFile.MIN_NUM_HFILE_PATH_LEVELS) {
      LOG.warn("Could not determine table and column family of the HFile "
          + "path " + path + ". Expecting at least "

      if (cfName.equals(HRegion.REGION_TEMP_SUBDIR)) {

        // the real CF name later.
