```

之后就是不停的循环,怪异的是 MyMapFunction2.java:39内容是
```

if (null != uniqMark.value() && uniqMark.value()) {

```

而报错的时间点距离任务启动差不多就是 12 小时,符合我设置的 valueState 的 ttl

```

@Override
public void open(Configuration parameters) throws Exception {
  ValueStateDescriptor<Boolean> descriptor = new
ValueStateDescriptor<>("uniqMark",
      TypeInformation.of(Boolean.class));
  StateTtlConfig ttlConfig = StateTtlConfig.newBuilder(Time.hours(1))
      .setUpdateType(UpdateType.OnCreateAndWrite)
      .setStateVisibility(StateVisibility.ReturnExpiredIfNotCleanedUp)
      .cleanupIncrementally(1000, false)
      .build();
  descriptor.enableTimeToLive(ttlConfig);
  uniqMark = getRuntimeContext().getState(descriptor);
}

```

所以我猜测在什么极端情况下会出现 valueState 自身变为 null 的情况么?(比如刚刚被清理的瞬间)?

求各位指正

Re: flink遇到 valueState 自身的 NPE

hi Kevin,

能贴一下MyMapFunction2.java:39 这里的代码吗? 从上面的日志看不出来是valueState是null呢。

Re: flink遇到 valueState 自身的 NPE

Benchao Li
我感觉这个地方好像没有道理会有`uniqMark`变成`null`,
除非是什么地方反序列化出来`StreamMap`,并且没有调用`StreamMap.open()`.
但是看起来`StreamTask`是可以保证先调用`open`,再调用operator的处理函数的。我也看不出来这个地方有什么问题。

Re: flink遇到 valueState 自身的 NPE

Kevin Liao
谢答
但还有一问题想请教:

当 valueState 触发 ttl 被回收后,这里的引用应该也会被 gc 掉,就会变成 null 了吧?难道是 operator 原来处理这个
key 的线程会被一并回收掉,下次这个 key 再来时其实已经是另外新生成的线程提供服务了(这样肯定要重新调用一次 open
方法)?看了代码但还没搞明白,求解惑,谢谢

Re: flink遇到 valueState 自身的 NPE

Yun Tang
Hi Kevin

State TTL 是清理的state中的数据条目entry,不是清理state在map函数中的对象本身。所以无论如何,作为value state对象的uniqMark 是不会因为TTL而变成null的。

我注意到你的作业即使发生failover之后,立刻恢复的时候,仍然遇到了这个NPE问题,我怀疑你实际运行的代码第39行并不是你贴出来的代码,很有可能是对应你的代码的第34行,也就是map方法的输入RDLog是null,这也符合作业成功restore之后,又再次立即遇到failover的场景,也就是处理到了非法“脏数据”,导致作业不断failover。建议你按照这个思路确认排除一下。

祝好
唐云

谢答
但还有一问题想请教:

当 valueState 触发 ttl 被回收后,这里的引用应该也会被 gc 掉,就会变成 null 了吧?难道是 operator 原来处理这个
key 的线程会被一并回收掉,下次这个 key 再来时其实已经是另外新生成的线程提供服务了(这样肯定要重新调用一次 open
方法)?看了代码但还没搞明白,求解惑,谢谢

Re: flink遇到 valueState 自身的 NPE

Kevin Liao
谢答,首先贴的代码确实是运行的程序

此外刚刚又通过打印 log 确认了 uniqMark == null 是 false

我现在的怀疑点是这个地方

if (null != uniqMark.value() && uniqMark.value()) {

第一处uniqMark.value()可以取到结果(不为 null),同时由于 ttl 策略会触发
clear,进而导致第二个uniqMark.value()取出来的就是 null
了(看来编译器没有对这种写法做优化,就是真实的执行了两次value()函数),追了下代码似乎可以支持我的猜测,所以准备明天验证下这个猜测

明天有消息同步,谢谢

Re: flink遇到 valueState 自身的 NPE

Yun Tang
Hi Kevin

帮你看了下代码,问题定位到了。
容易发生的原因在于你的可见性配置成了 ReturnExpiredIfNotCleanedUp,而Flink会先发现数据expire,然后触发clear操作,之后再返回expire的数据 [1]。建议修改一下第39行的判断条件,每次取数据时都做是否为null的判断。


[1] https://github.com/apache/flink/blob/dba5b9e0138b667c3ecd32f7b16645d531477720/flink-runtime/src/main/java/org/apache/flink/runtime/state/ttl/AbstractTtlDecorator.java#L96

祝好
唐云

Subject: Re: flink遇到 valueState 自身的 NPE

谢答,首先贴的代码确实是运行的程序

此外刚刚又通过打印 log 确认了 uniqMark == null 是 false

我现在的怀疑点是这个地方

if (null != uniqMark.value() && uniqMark.value()) {

第一处uniqMark.value()可以取到结果(不为 null),同时由于 ttl 策略会触发
clear,进而导致第二个uniqMark.value()取出来的就是 null
了(看来编译器没有对这种写法做优化,就是真实的执行了两次value()函数),追了下代码似乎可以支持我的猜测,所以准备明天验证下这个猜测

明天有消息同步,谢谢

Re: flink遇到 valueState 自身的 NPE

Kevin Liao
谢谢,同定位到这个地方

已改成

```

Boolean existed = uniqMark.value();
// 如果是重复出现则被过滤掉
if (null != existed && existed) {
  return null;
}
uniqMark.update(true);

```

问题解决

> 我注意到你的作业即使发生failover之后,立刻恢复的时候,仍然遇到了这个NPE问题,我怀疑你实际运行的代码第39行并不是你贴出来的代码,很有可能是对应你的代码的第34行,也就是map方法的输入RDLog是null,这也符合作业成功restore之后,又再次立即遇到failover的场景,也就是处理到了非法“脏数据”,导致作业不断failover。建议你按照这个思路确认排除一下。
