在写入Tair的Bolt里报错

数据量小时没有问题，只要数据量稍大一点，就会报错：Failed to get Grouper of __master_task_heartbeat when  emit from tairbolt，求指点


Tair操作对象初始化工作在Bolt类的prepare方法里

private TairOperatorImpl tairOperator;
@Override
public void prepare(Map stormConf, TopologyContext context, OutputCollector collector) {
    this.collector = collector;
    this.tairOperator = new TairOperatorImpl(RaceConfig.TairConfigServer, RaceConfig.TairSalveConfigServer,
                RaceConfig.TairGroup, RaceConfig.TairNamespace);
}
