apache-spark - 无法在 Mac 上以独立模式运行 Spark 1.2

Question

我正在尝试通过在 MacBook Pro (10.9.2) 上以独立模式运行 Spark 来学习 Spark。我按照此处的说明下载并构建了它:

http://spark.apache.org/docs/latest/building-spark.html

然后我按照此处的说明启动了主服务器:

https://spark.apache.org/docs/latest/spark-standalone.html#starting-a-cluster-manually

这很有效，尽管我必须将以下行添加到我的 SPARK_HOME/conf/spark-env.sh 文件中才能使其成功启动:

export SPARK_MASTER_IP="127.0.0.1"

但是，当我尝试执行此命令来启动工作程序时:

./bin/spark-class org.apache.spark.deploy.worker.Worker spark://127.0.0.1:7077

失败并出现以下错误:

我不明白对 IP 地址 10.252.181.130 的引用。它没有出现在我能够找到的 Spark 代码/配置中的任何位置，并且谷歌搜索它也没有出现任何结果。当我启动主服务器时，我注意到日志文件中的这一行:

15/01/26 16:27:18 INFO MasterWebUI: Started MasterWebUI at http://10.252.181.130:8080

我查看了 MasterWebUI(以及它扩展的 WebUI)的 Scala 源代码，并注意到它们似乎从名为 SPARK_PUBLIC_DNS 的环境变量获取该 IP 地址。我尝试在我的 Spark-env.sh 脚本中将该变量设置为 127.0.0.1，但这不起作用。事实上，它阻止了我的主服务器启动:

(请注意，LM-PDX-00871419 是我的 Mac 的主机名。)

所以现在我有点难住了。我非常感谢任何关于下一步该去哪里的建议。

如果您使用 IntelliJ IDEA，了解可以在运行/调试配置中将环境变量 SPARK_LOCAL_IP 设置为 127.0.0.1 可能会有所帮助。
