1.0.6版本，修改分片参数后，导致仅单一节点执行的监听报异常

[gaoyaqiu]

资源: 1台服务器(job和zk在一起), 不能发图我就发代码了。
代码如下：

1. main方法
   public static void main(final String[] args) {
   ZookeeperConfiguration zkConfig = new ZookeeperConfiguration("localhost:2181", "cy-job", 1000, 3000, 3);
   CoordinatorRegistryCenter regCenter = new ZookeeperRegistryCenter(zkConfig);
   regCenter.init();

 JobConfiguration jc1 = new JobConfiguration("999", SimpleJobDemo.class, 3, "0/10 * * * * ?");           
 jc1.setShardingItemParameters("0=a,1=b,2=c");                                                           
 new JobScheduler(regCenter, jc1, new OnceJobListener(1000, 10000)).init();                              

}

1. 监听使用的是仅单一节点执行的监听
   public class OnceJobListener extends AbstractDistributeOnceElasticJobListener {

   public OnceJobListener(long startedTimeoutMilliseconds, long completedTimeoutMilliseconds) {
   super(startedTimeoutMilliseconds, completedTimeoutMilliseconds);
   }

   @OverRide
   public void doBeforeJobExecutedAtLastStarted(JobExecutionMultipleShardingContext shardingContext) {
   System.out.println("任务执行前监听");
   }

   @OverRide
   public void doAfterJobExecutedAtLastCompleted(JobExecutionMultipleShardingContext shardingContext) {
   System.out.println("任务执行后监听");
   }
   }

2. 启动job
   监听日志正常输出

3. 修改分片参数
   我是在监控平台帮分片修改为1，分片序号修改为0=a，保存。

4. 控制台监听报异常
