Description

HelpCommand class firstly retrieves the documentation in tajo.apache.org. Its approach looks good. But, it is likely to take too long time (usually 1-3 seconds) at first time. We should resolve it or remove it.

try {
        URL u = new URL("http://tajo.apache.org/docs/"+ tajoVersion + "/");
        HttpURLConnection huc =  (HttpURLConnection) u.openConnection();
        huc.setConnectTimeout(1000);
        huc.setReadTimeout(1000);
        huc.setRequestMethod("HEAD");
        if(huc.getResponseCode() == HttpURLConnection.HTTP_OK) {
          docVersion = tajoVersion;
        } else {
          docVersion = docDefaultVersion;
        }
