我在Hadoop 2.7群集上安装了Spark 1.4.1。
我已经启动了SparkR shell而没有错误：
bin/sparkR --master yarn-client
我没有错误地运行R命令（来自spark.apache.org的介绍性示例）：
df <- createDataFrame(sqlContext, faithful)
当我运行命令时：
head(select(df, df$eruptions))
我在执行程序节点上的15/09/02 10:08:29收到以下错误：
“Rscript执行错误：没有这样的文件或目录”。
任何提示都将不胜感激。 除了SparkR之外的Spark任务在我的YARN群集上运行正常。 已安装R 3.2.1并在驱动程序节点上运行正常。
