Description

in  org.apache.iotdb.db.protocol.mqtt.PayloadFormatManager#init

=============================

  private static void init() {
    ServiceLoader<PayloadFormatter> formats = ServiceLoader.load(PayloadFormatter.class);
    for (PayloadFormatter format : formats)

{       map.put(format.getName(), format);     }

  }

=============================

Here, mqtt palyload format parser is provided by plugin that customers can dev.

But it has no classloader isolation, which can cause jar version conflict among iotDB and plugins .
