2. 解决方案

第一步：拷贝文件

cp /opt/cloudera/parcels/CDH/etc/spark/conf.dist/* /opt/cloudera/parcels/SPARK2/etc/spark2/conf.dist/

第二步：配置spark-env.sh文件

vim /opt/cloudera/parcels/SPARK2/etc/spark2/conf.dist/spark-env.sh

第三步：指定文件目录

export SPARK_DIST_CLASSPATH=$(hadoop classpath) //指定hadoop class文件目录
export HADOOP_CONF_DIR=/etc/hadoop/conf   //指定hadoop配置文件目录
