Answer 1

https://issues.apache.org/jira/browse/SPARK-1378

最后是自己下了那个jar放到～/.m2里才搞定

Answer 2

由于 https://repo.eclipse.org/content/repositories/paho-releases 不能访问，
org.eclipse.paho:org.eclipse.paho.client.mqttv3:jar:1.0.1 中央库没有，换成1.0.2试试：

vim /data0/software/*spark-1.6.2/external/mqtt/pom.xml*
   <dependency>
      <groupId>org.eclipse.paho</groupId>
      <artifactId>org.eclipse.paho.client.mqttv3</artifactId>
      <version>**1.0.2**</version>
    </dependency>
