Spark 1.6.1 SASL

Question

我想知道是否有人让SASL在YARN上使用Spark 1.6.1？

基本上Spark文档指出，您只需要启用3个参数：

spark.authenticate.enableSaslEncryption=true    
spark.network.sasl.serverAlwaysEncrypt=true
spark.authenticate=true

http://spark.apache.org/docs/latest/security.html

然而，在使用--masteryarn和--deploymode客户端启动我的spark作业时，我在我的spark-executors日志中看到了以下内容：

我仍在对此进行故障排除。然而，如果有人以前见过这个，那就太棒了。

您还需要在YARN中设置spark.authenticate=true。

摘自Spark代码库中的YarnShuffleService.java：

 * The service also optionally supports authentication. This ensures that executors from one
 * application cannot read the shuffle files written by those from another. This feature can be
 * enabled by setting `spark.authenticate` in the Yarn configuration before starting the NM.
 * Note that the Spark application must also set `spark.authenticate` manually and, unlike in
 * the case of the service port, will not inherit this setting from the Yarn configuration. This
 * is because an application running on the same Yarn cluster may choose to not use the external
 * shuffle service, in which case its setting of `spark.authenticate` should be independent of
 * the service's.

您可以通过在hadoop配置中向core-site.xml添加以下内容来实现这一点。

<property>
    <name>spark.authenticate</name><value>true</value>
</property>
