Flink 在IDEA执行时的webui

不过Flink IDEA中执行的webui 需要 flink-runtime-web 包的支持

pom 如下：

<dependency>
            <groupId>org.apache.flink</groupId>
            <artifactId>flink-runtime-web_${scala.binary.version}</artifactId>
            <version>${flink.version}</version>
</dependency>

启动日志如下：

2019-08-13 09:52:58,907 WARN  org.apache.flink.runtime.webmonitor.WebMonitorUtils           - Log file environment variable 'log.file' is not set.

flink webui监听地址如下：  http://localhost:2841

打开对应地址：

进入job：

Metrics 也正常：

不过 logs 和 Stdout 是没有值的

如果配置了pom 还是没有webui，先检查下端口，确定没问题，可以查看下下面的链接：
