flink-kafka-elasticsearch部署在纱线上

Question

独立模式没有问题。但是，纱线模式无法正常工作。我在flink classpath（flink / lib）中添加了hadoop jar。我在jira上看到了一些讨论，例如

• https://issues.apache.org/jira/browse/FLINK-3373

• https://issues.apache.org/jira/browse/FLINK-6126

• https://issues.apache.org/jira/browse/FLINK-4587

在flink 1.2中已解决？

flink版本：1.9.1

hadoop / yarn版本：2.6.0

elasticsearch版本：6.8.1

我使用Flink Elasticsearch connector解决了问题。我昨天通过实现RichSinkFunction做到了。
