使用flink同步数据出现错误Checkpoint expired before completing.

任务超时了：

重新把任务配置参数，配置如下：

//开启CK
env.getCheckpointConfig().setCheckpointTimeout(60000);
//设置定期安排检查点的时间间隔。
env.getCheckpointConfig().setCheckpointInterval(60000);
//设置可能同时进行的检查点尝试的最大次数
env.getCheckpointConfig().setMaxConcurrentCheckpoints(500);
//设置检查点尝试之间的最小暂停时间。
env.getCheckpointConfig().setMinPauseBetweenCheckpoints(500);

或者修改

flink的配置文件flink-conf.yaml
