flinksql流计算任务非正常结束怎么处理？

我启动了yarn-session：bin/yarn-session.sh -jm 1g -tm 4g -s 4 -qu root.flink -nm fsql-cli 2>&1 &

然后通过sql-client，提交了一个sql：

主要逻辑是将一个kafka表和一个hive维表做join，然后将聚合结果写到mysql中。

运行过程中，经常出现短则几个小时，长则几十个小时后，任务状态变为succeeded的情况，如图：https://s1.ax1x.com/2020/06/29/Nf2dIA.png

日志中能看到INFO级别的异常，15:34任务结束时的日志如下： 2020-06-29 14:53:20,260 INFO org.apache.flink.api.common.io.LocatableInputSplitAssigner - Assigning remote split to host uhadoop-op3raf-core12 2020-06-29 14:53:22,845 INFO org.apache.flink.runtime.executiongraph.ExecutionGraph - Source: HiveTableSource(vid, q70) TablePath: dw.video_pic_title_q70, PartitionPruned: false, PartitionNums: null (1/1) (68c24aa5 9c898cefbb20fbc929ddbafd) switched from RUNNING to FINISHED. 2020-06-29 15:34:52,982 INFO org.apache.flink.runtime.entrypoint.ClusterEntrypoint - Shutting YarnSessionClusterEntrypoint down with application status SUCCEEDED.
