Apache spark 在本地主机上运行的Spark BlockManager

我有一个简单的脚本文件，我正试图在模拟教程的spark shell中执行

我的namenode和mesos主机位于172.24.51.171，我的ip地址是172.24.51.142。我已将这些行保存到一个文件中，然后使用以下命令启动该文件：

/opt/spark-1.3.0-bin-hadoop2.4/bin/spark-shell -i WordCount.scala

我的远程执行器都会因以下类似错误而死亡：

此失败发生在我运行errors.count（）命令之后。在我的shell的前面，在创建新的SparkContext后，我看到以下行：

15/04/08 14:31:18 INFO NettyBlockTransferService: Server created on 48554
15/04/08 14:31:18 INFO BlockManagerMaster: Trying to register BlockManager

15/04/08 14:31:18 INFO BlockManagerMaster: Registered BlockManager

15/04/08 14:31:18信息NettyBlockTransferService:在48554上创建的服务器
15/04/08 14:31:18信息BlockManager管理员：正在尝试注册BlockManager

15/04/08 14:31:18信息BlockManager管理员：已注册的BlockManager

我猜发生的是Spark将BlockManager的地址记录为localhost:48554，然后发送给所有试图与其localhost:48554对话的执行者，而不是端口48554上的驱动程序ip地址为什么spark使用localhost作为BlockManager的地址而不是spark.driver.host？

补充资料

中有一个spark.blockManager.port，但没有spark.blockManager.host？只有一个spark.driver.host，您可以看到我在SparkConf中设置了它

可能与此有关，尽管这似乎是一个网络问题。我的网络配置了DNS，一切正常

尝试通过

sparkConf

对象设置

SPARK\u LOCAL\u IP

（在命令行上）或

SPARK.LOCAL.IP

。

在调用SPARK shell（或添加SPARK defaults.conf）时，可以尝试使用--Master参数提供SPARK主地址。我有一个类似的问题（见我的帖子），当在shell中动态创建上下文时，BlockManager似乎会在localhost上侦听

日志：

• 使用原始上下文时（侦听主机名） BlockManagerInfo:在ubuntu64server2:33301的内存中添加了广播\u 1\u片段0

• 创建新上下文时（在本地主机上侦听） BlockManagerInfo:在本地主机40235上的内存中添加了广播\u 1\u片段0

---

我必须连接到Cassandra群集，并且能够通过在spark-defaults.conf中提供spark.Cassandra.connection.host并在spark shell中导入com.datasax.spark.connector.u.

Hi maasg--根据配置页面，没有效果，spark.local.ip不是spark 1.2.1或spark 1.3.0中配置的一部分。请参阅我的问题中的链接“当在shell中动态创建上下文时，BlockManager在本地主机上侦听”。这也是我的结论，但似乎是违反直觉的行为。在spark-defaults.conf中设置spark.master为我解决了这个问题
