Hi, 你可以看下下面这个JIRA[1]，看下是不是你所遇到的问题。
[1] https://issues.apache.org/jira/browse/FLINK-19675 Best, Xingbo Evan <[email protected]> 于2020年11月2日周一 下午2:46写道： > 首先你的邮件里有很多“ ” 符号，很影响阅读 > 根据你的邮件大致判断，是你的where用法用错了，貌似是你的where里边写了两个条件，建议你查一下pyflink的api，查询where的用法 > > > > > 发件人： 洗你的头 > 发送时间： 2020-11-02 10:15 > 收件人： user-zh > 主题： 回复： pyflink的where该如何使用？如何筛选？ > 您好， > 我是想在数据处理的过程中，对输出进行筛选，然后使用的是where方法，请问我应该如何更改代码呢？（感谢您的回答） > 报错如下： > --------------------------------------------------------------------------- > Py4JJavaError > Traceback (most recent call > last) >
