Question

我们正在使用ambari，pyspark，sql和scala管理的hdp沙盒上运行齐柏林飞艇，但％spark2.r却无法运行。有什么想法吗？ -我发誓到处都是。

我尝试签入SPARK_HOME = / usr / hdp / current / spark2-client /，但如果是正确的文件夹，则为idk-如何检查？我在沙盒上安装了Rstudio，它工作正常，当我尝试在盒子的外壳中运行R代码时，它也能正常工作。我确定已经安装了R。

%spark2.r
foo <- TRUE
print(foo)
bare <- c(1, 2.5, 4)
print(bare)
double <- 15.0
print(double)
