我跟着这趟旅行http://hortonworks.com/hadoop-tutorial/using-apache-spark-hdp/ 在HDP2.2上安装spark。
但它告诉我dfs拒绝了我的联系！我的命令是：

./bin/spark-submit --class org.apache.spark.examples.SparkPi --master yarn-cluster --num-executors 3 --driver-memory 512m  --executor-memory 512m  --executor-cores 1  lib/spark-examples*.jar 10

日志如下：

有人这么说(http://tiku.io/questions/4795653/unable-to-run-spark-1-0-sparkpi-on-hdp-2-0)，但我不明白。
我的环境是

HDP: 2.2
Ambari: 1.7
Spark 1.2

您必须修改管理调度程序的参数，我会根据集群中的可用内存容量来增加它。在Yarn设置中：
yarn.scheduler.maximun-allocation-mb=3072（或更大的数量）
