-----------------------------------

Thanks for [~wenqiao], but I found that the new configuration can not be compatible with the old, I think it is best to be compatible, in my own code I modified the TaildirSource selectByKeys method.

private Table<String, String, String> selectByKeys(Map<String, String> map, String[] keys) {
    Table<String, String, String> result = HashBasedTable.create();
    for (String key : keys) {
      if (map.containsKey(key + FILE_GROUPS_SUFFIX_DIR) && map.containsKey(key + FILE_GROUPS_SUFFIX_FILE)) {
        result.put(key, FILE_GROUPS_SUFFIX_DIR.substring(1), map.get(key + FILE_GROUPS_SUFFIX_DIR));
        result.put(key, FILE_GROUPS_SUFFIX_FILE.substring(1), map.get(key + FILE_GROUPS_SUFFIX_FILE));
      } else if (map.containsKey(key)) {
        // translate the old configuration 
        File fg = new File(map.get(key));
        Log.warn("{} is deprecated. Please use the parameter {}",
          "filegroups." + key,
          new StringBuffer("filegroups.").append(key)
            .append(FILE_GROUPS_SUFFIX_DIR)
            .append(" and filegroups.")
            .append(key)
            .append(FILE_GROUPS_SUFFIX_FILE));
        result.put(key, FILE_GROUPS_SUFFIX_DIR.substring(1), fg.getParent());
        result.put(key, FILE_GROUPS_SUFFIX_FILE.substring(1), fg.getName());
      } else {
        Preconditions.checkState(map.containsKey(key + FILE_GROUPS_SUFFIX_DIR),
          "Mapping for tailing files is empty or invalid: '" + FILE_GROUPS_PREFIX
          + (key + FILE_GROUPS_SUFFIX_DIR) + "'");
        Preconditions.checkState(map.containsKey(key + FILE_GROUPS_SUFFIX_FILE),
          "Mapping for tailing files is empty or invalid: '" + FILE_GROUPS_PREFIX
            + (key + FILE_GROUPS_SUFFIX_FILE + "'"));
      }
    }
    return result;
  }

> In our log management project, we wan't to track many log files like this:
> /app/dir1/log.*
>  /app/dir2/log.*
> ...
> /app/dirn/log.*
> But TaildirSource can't support wildcards in filegroup directory name. The following config is expected:
> a1.sources.r1.filegroups.fg = /app/\*/log.*
