安装spark单机环境

(假定已经装好的hadoop，不管你装没装好，反正我是装好了)

1 下载spark安装包 http://spark.apache.org/downloads.html

下载spark-1.6.1-bin-without-hadoop.tgz

2 将spark包解压到自己指定目录

然后在spark中指定hadoop jar包的路径

先执行 hadoop classpath把输出内容记下来

在spark conf路径下新建spark-env.sh

然后输入以下内容:(注意：：：：：：：把hadoop classpath 替换为刚才命令的输出内容)

### in conf/spark-env.sh ###

# If 'hadoop' binary is on your PATH
export SPARK_DIST_CLASSPATH=$(hadoop classpath)

# With explicit path to 'hadoop' binary
export SPARK_DIST_CLASSPATH=$(/path/to/hadoop/bin/hadoop classpath)

# Passing a Hadoop configuration directory
export SPARK_DIST_CLASSPATH=$(hadoop --config /path/to/configs classpath)

3 然后你就可以执行pyspark之类的进入命令行了
