我一直在尝试使用 h2o(rsparkling) 运行 Spark 2.2，master=yarn 但是当我运行 h2o_context(sc) 我获取异常:

我也尝试过 spark 2.0.0(通过 sparklyr 函数安装:spark_install)。然后搭配rsparkling和h2o。当我设置 master="local" 时它起作用了，但是当我设置 master="yarn"

同样，我尝试了 Spark 1.6，它运行良好(也是 master=yarn)。

有什么想法吗？

这是我的代码:

library(sparklyr)
library(rsparkling)
library(h2o)


Sys.setenv(SPARK_HOME='/usr/hdp/2.6.3.0-235/spark2')

sc <- spark_connect(master = "yarn")
h2o_context(sc)

我尝试使用(类似的)install.packages("h2o", type = "source", repos = "http://h2o-release.s3.amazonaws.com/h2o/rel-tverberg/2/R ") 安装各种不同版本的 h2o，但每次错误都没有改变。

最佳答案

感谢错误报告!它应该已经在 Sparkling Water 的 master 分支中修复，它将成为下一个版本的一部分(预计下周发布)。

谢谢， 导航深度
