spark streaming kafka运行出错,找不到 com/yammer/metrics/Metrics
kafka是CDH里面的,版本是0.8.2.0-1.kafka1.3.0.p0.29,CDH是5.4.2版本,hadoop是2.6.0,spark是1.5版本.ubuntu系统使用intellij14,已经与spark集群配置了hosts以下是运行代码

看看本地库中是否有
本地库中.m2/repository/com/yammer/metrics目录中没有这个jar包,但是有metrics-core和metrics-parent这两个文件夹在pom.xml文件中也添加了
<dependency>
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming-zeromq_2.10</artifactId>
<version>1.5.0</version>
</dependency>
依赖还是不行

本地库中.m2/repository/com/yammer/metrics目录中没有这个jar包,但是有metrics-core和metrics-parent这 ...
自己下载放到本地库中试试，本地库中找不到肯定报错的
楼主是不是这个依赖没有加呢
