Question

我想知道是否有人让SASL在YARN上使用Spark 1.6.1？

基本上Spark文档声明您只需要启用3个参数：

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

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

但是，在使用--master yarn和--deploy-mode客户端启动我的spark作业后，我在spark执行器日志中看到以下内容：

我还在排除故障。但是，如果有人以前看过这个，那就太棒了。

Answer 1

您还需要在YARN中设置* 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.。

摘自Spark代码库中的YarnShuffleService.java：

core-site.xml

您可以将以下内容添加到hadoop配置中的<property> <name>spark.authenticate</name><value>true</value> </property>。
