按照网上的spark安装教程安装完之后,启动spark-shell,出现如下报错:

报错原因:

经过各种搜狗,Stack Overflow终于发现原因:

从spark1.4以后,所有spark的编译都是没有将hadoop的classpath编译进去的,所以必须在spark-env.sh中指定hadoop中的所有jar包。

具体设置如下:

在spark-evn.sh中添加

# 这里实际上就是执行一条hadoop的命令,将hadoop的classpath引一下
export export SPARK_DIST_CLASSPATH=$(${HADOOP_HOME}/bin/hadoop classpath)

 

具体的说明:
