无法解析主网址：“spark.bluemix.net”

我试图连接到IBM的星火作为Bluemix从RStudio我的台式机上运行的运行的服务。无法解析主网址：“spark.bluemix.net”

我抄config.yml从IBM的数据科学实验运行自动配置RStudio环境：

default: 
    method: "shell" 

CS-DSX: 
    method: "bluemix" 
    spark.master: "spark.bluemix.net" 
    spark.instance.id: "myinstanceid" 
    tenant.id: "mytenantid" 
    tenant.secret: "mytenantsecret" 
    hsui.url: "https://cdsx.ng.bluemix.net"

我试图连接，像这样：

install.packages("sparklyr") 

library(sparklyr) 
spark_install(version = "1.6.2") # installed spark to '~/Library/Caches/spark/spark-1.6.2-bin-hadoop2.6' 

spark_home = '~/Library/Caches/spark/spark-1.6.2-bin-hadoop2.6' 

config = spark_config(file = "./config.yml", use_default = FALSE, config = "CSX-DSX") 

sc <- spark_connect(spark_home = spark_home, config = config)

错误：

17/03/07 09:36:19 ERROR SparkContext: Error initializing SparkContext. 
org.apache.spark.SparkException: Could not parse Master URL: 'spark.bluemix.net' 
    at org.apache.spark.SparkContext$.org$apache$spark$SparkContext$$createTaskScheduler(SparkContext.scala:2735)

    at org.apache.spark.SparkContext.getOrCreate(SparkContext.scala) 
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) 
    ...

stackover上还有其他一些问题流类似的错误消息，但它们不尝试连接到在Bluemix上运行的Spark服务。

更新1

我已经改变了我config.yml看起来像这样：

default: 
    method: "bluemix" 
    spark.master: "spark://spark.bluemix.net:7070" 
    spark.instance.id: "7a4089bf-3594-4fdf-8dd1-7e9fd7607be5" 
    tenant.id: "sdd1-7e9fd7607be53e-39ca506ba762" 
    tenant.secret: "6146a713-949f-4d4e-84c3-9913d2165b9e" 
    hsui.url: "https://cdsx.ng.bluemix.net"

...和我的连接代码看起来像这样：

install.packages("sparklyr") 
library(sparklyr) 
spark_install(version = "1.6.2") 
spark_home = '~/Library/Caches/spark/spark-1.6.2-bin-hadoop2.6' 
config = spark_config(file = "./config.yml", use_default = FALSE) 
sc <- spark_connect(spark_home = spark_home, config = config)

但是，错误是现在：

Error in force(code) : 
    Failed during initialize_connection: java.lang.NullPointerException 
    at org.apache.spark.SparkContext.<init>(SparkContext.scala:583) 
    at org.apache.spark.SparkContext$.getOrCreate(SparkContext.scala:2281)
