token (HDFS_DELEGATION_TOKEN token 1377***for user***) can't be found in cache 疑问: flink on yarn在HADOOP Delegation token清除后,是如何更新的呢?是生成了新的token吗? 如果生成了新的token,为何am attempt 时,还会继续获取已清除的这个token(13770506) 这个故障是否和nodemanager容器化部署有关?nodeman...
博主有解决吗，我也遇到了这个问题
默认情况下数据源是非并行的,用户需要实现ParallelSourceFunction接口或者继承RichParallelSourceFunction来实现可并行的数据源。 addSource方法将一个StreamFunction封装为StreamSource,当数据源开始执行时调用SourceFunction#run(SourceContext<T> ctx)方法,持续地向SourceContext发送生成的数据。 代码语言:javascript 复制 public...

由于FLINK STATE index type是in-memory的,都有可能导致flink任务的堆内存爆掉,解决方法是使用BUCKET index type 特别是当表很大的时候,第一次snapshot同步会消耗比较多的资源以及时间,这时候如果使用的是hudi sink的话建议将hudi的index.type设置成BUCKET,因为flink默认的index type是FLINK_STATE,FLINK_STATE默认是...
