------------------------------------
改了例子之后也最好在文档内说明如果遇到类似问题的原因；
FQA也好，提醒用户不要这样顺序启动也好。

> Key: IOTDB-2274
> URL: https://issues.apache.org/jira/browse/IOTDB-2274
> Project: Apache IoTDB
> Issue Type: Bug
> Components: Core/Server
> Affects Versions: 0.13.0-SNAPSHOT
> Reporter: 刘珍
> Assignee: Steve Yurong Su
> Priority: Minor
> Labels: 0.13.0
>
> 复现流程：
> 1. 不开启mqtt服务
> ext/trigger/trigger-example-0.13.0-SNAPSHOT.jar
> cli创建时间序列/触发器：
> create timeseries root.lz.dev.trigger_s1 with datatype=int32;
> CREATE TRIGGER "alert-listener-t1 "
> AFTER INSERT
> ON root.lz.dev.trigger_s1
> AS 'org.apache.iotdb.trigger.TriggerExample'
> WITH (
> 'lo' = '0',
> 'hi' = '100.0'
> );
> 创建触发器卡住，一直连接mqtt服务。
> 2. 开启mqtt服务，重启iotdb，{color:#DE350B}*iotdb卡住*{color}（一直不出现enjoy）
