我一直在尝试在亚马逊私有云上的一台干净的ubuntu14.04机器上设置hadoop/spark/sparkling water。以根的身份做每件事。我成功地获得了java-6、scala2.10.5，然后wget并解包了hadoop2.6、spark1.2.1和sparklingwater0.2.1-47。
我将hadoop\u home和spark\u home导出到正确的目录，并运行bin/sparkling shell：

import org.apache.spark.h2o._
import org.apache.spark.examples.h2o._
val h2oContext = new H2OContext(sc).start()

接下来是大量的开始任务x/完成任务x输出，然后是

java.lang.IllegalArgumentException: Cannot execute H2O on all Spark executors:
  numH2OWorkers = -1"
  executorStatus = (0,false),(1,false),(2,false),(0,false),(1,false),(2,false),(1,false),(1,false),(1,false),(1,false),(1,false),(1,false),(1,false),(1,false),(0,false),(1,false),(0,false),(1,false),(1,false),(0,false),(1,false),(0,false),(1,false),(1,false),(0,false),(0,false),(1,false),(1,false),(0,false),(0,false),(2,false),(2,false),(1,false),(0,false),(1,false),(0,false),(2,false),(1,false),(2,false),(1,false),(0,false),(1,false),(2,false),(0,false),(1,false),(2,false),(1,false),(2,false),(0,false),(2,false),(1,false),(0,false),(1,false),(0,false),(1,false),(2,false),(0,false),(2,false),(1,false),(1,false),(0,false),(2,false),(0,false),(2,false),(1,false),(1,false),(0,false),(1,false),(1,false),(2,false),(0,false),(2,false),(1,false),(1,false),(0,false),(2,false),(0,false),(2,false),(1,false),(1,false),(0,false),(2,false),(0,false),(2,false),(1,false),(0,false),(1,false),(2,false),(0,false),(1,false),(2,false),(1,false),(0,false),(2,false),(0,false),(2,false),(1,false),(2,false),(1,false),(2,false),(0,false),(1,false),(1,false),(2,false),(0,false),(2,false),(0,false),(1,false),(1,false),(2,false),(0,false),(2,false),(1,false),(2,false),(0,false),(1,false),(0,false),(2,false),(0,false),(1,false),(1,false),(2,false),(0,false),(2,false),(0,false),(1,false),(2,false),(1,false),(2,false),(0,false),(0,false),(1,false),(2,false),(2,false),(1,false),(1,false),(0,false),(0,false),(2,false),(2,false),(1,false),(0,false),(1,false),(2,false),(0,false),(2,false),(1,false),(0,false),(2,false),(1,false),(2,false),(0,false),(1,false),(1,false),(2,false),(0,false),(2,false),(2,false),(1,false),(1,false),(0,false),(2,false),(0,false),(1,false),(2,false),(0,false),(1,false),(2,false),(2,false),(1,false),(0,false),(0,false),(2,false),(1,false),(2,false),(0,false),(0,false),(1,false),(2,false),(1,false),(2,false),(1,false),(2,false),(0,false),(1,false),(0,false),(2,false),(1,false),(0,false),(1,false),(2,false),(0,false),(2,false),(0,false),(1,false),(0,false),(1,false),(2,false),(1,false),(2,false)

有人能指出我可能做错了什么和/或遗漏了什么吗？如果需要/有帮助，我可以发布我的精确设置脚本。
