当我输入以下命令时，我可以运行spark
$ pyspark
和
$ pyspark --master local [2]
但不是在我运行这个时 -
$ pyspark --master yarn-client
它为我提供了一个巨大的堆栈跟踪，下面给出了更多或更清晰可用的here。
$ pyspark --master yarn-client

我在伪分布式模式下安装了hadoop，启动了dfs.sh和yarn.sh.他们似乎正在运行，因为$ jps给了我 -

15658 Jps
14171 ResourceManager
13631 NameNode
我不在虚拟机上，我使用的是ubuntu和Hadoop 2.7，我正在使用spark 2.0.1。
spark-env.sh中的条目 -
export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
export YARN_CONF_DIR=/usr/local/hadoop/etc/hadoop
bashrc看起来像这样 -
