Flink 1.12.0 隔几个小时Checkpoint就会失败

Hi 大家好

我用的Flink on yarn模式运行的一个任务，每隔几个小时就会出现一次错误

然后就自己恢复了。用的是Unaligned Checkpoint，rocksdb存储后端，在这个错误前后也没有什么其他报错信息。从Checkpoint的metrics看，总是剩最后一个无法完成，调整过parallelism也无法解决问题。

谢谢大家！

Re: Flink 1.12.0 隔几个小时Checkpoint就会失败

设置下检查点失败不影响任务呀，你这貌似还导致任务重启了？

回复: Flink 1.12.0 隔几个小时Checkpoint就会失败

哦哦，我看到了有个

setTolerableCheckpointFailureNumber

之前不知道有这个方法，倒是可以试一下，不过我就是不太理解为什么会失败，也没有任何报错

设置下检查点失败不影响任务呀，你这貌似还导致任务重启了？

从日志看 checkpoint 超时了，可以尝试看一下是哪个算子的哪个并发没有做完 checkpoint，可以看看这篇文章[1] 能否帮助你

Re: Flink 1.12.0 隔几个小时Checkpoint就会失败

In reply to this post by Frost Wong

你好，问题定位到了吗？
我也遇到了相同的问题，感觉和checkpoint interval有关
我有两个相同的作业（checkpoint interval
设置的是3分钟），一个运行在flink1.9，一个运行在flink1.12，1.9的作业稳定运行，1.12的运行5小时就会checkpoint
制作失败，抛异常 org.apache.flink.util.FlinkRuntimeException: Exceeded checkpoint
tolerable failure threshold.
当我把checkpoint interval调大到10分钟后，1.12的作业也可以稳定运行，所以我怀疑和制作间隔有关。
看到过一个issuse，了解到flink1.10后对于checkpoint机制进行调整，接收端在barrier对齐时不会缓存单个barrier到达后的数据，意味着发送方必须在barrier对齐后等待credit
feedback来传输数据，因此发送方会产生一定的冷启动，影响到延迟和网络吞吐量。但是不确定是不是一定和这个相关，以及如何定位影响。

Re: Flink 1.12.0 隔几个小时Checkpoint就会失败

你好，我也遇到了这个问题，你的checkpoint是怎么配置的，可以参考一下吗

回复：Flink 1.12.0 隔几个小时Checkpoint就会失败

唉，这个问题着实让人头大，我现在还没找到原因。你这边确定了跟我说一声哈😊
