jupyter-notebook 以yarn模式运行的出现的问题及解决方法
之前用pyspark虚拟机只跑了单机程序，现在想试试分布式运算。
在做之前找了书和博客来看，总是有各种各样的问题，无法成功。现在特记录一下过程：
这里一共有两个虚拟机，一个做master,一个做slave1
虚拟机slave1安装spark
slave1之前已经安装了hadoop，并且可以成功进行Hadoop集群运算。这里就不多说了。
将master的spark安装包复制到slave1,
（1）进入到spark/conf文件夹中，将slaves.template复制成slaves,在里面添加slave1
（2）增加路径到/etc/profile
master与slave1都要做（1），（2）的步骤
slave1安装anaconda
可以用scp直接将master的anaconda复制过来，接下来修改/etc/profile就可。上面的图已经显示了修改的内容
启动，这时候遇到了好多问题
在master终端输入start-all.sh,使用jps查看，master和slave1都能正常启动
在master终端输入
HADOOP_CONF_DIR=/hadoop/hadoop/etc/hadoop PYSPARK_DRIVER_PYTHON="jupyter" PYSPARK_DRIVER_PYTHON_OPTS="notebook" MASTER=yarn-client pyspark
看资料说，如果没有在spark.env.sh中配置HADOOP_CONF_DIR，需要像上面代码在终端写出。这时候，jupyter-notebook可以成功启动，但是我在其中写入sc.master看它是何种模式运行时，却给我报了好多错误

这里主要出现了两个错误：
（1）
18/11/20 19:16:11 ERROR spark.SparkContext:

分别将这两个错误百度下
有的说是内存不足，有的说是需要两个内核
对于内存不足，在yarn-site.xml增加两个点
就是下面图片上的最后两个点
又修改虚拟机设置给slave1增加了两个处理器，使它变成两个核
然而仍旧出现相同的错误
继续修改，中间不知道修改了什么，再次运行
出现了不一样的错误

继续按照日志给出的信息继续寻找，
当我用

于是重新格式化namenode，
因为上面提到hdfs,我有修改了一下hdfs-site.xml。将里面的replication值从1变到2
再一次start-all.sh,
[root@master bin]# hadoop dfsadmin -report
