slaves

$ vim slaves

所有节点配置环境

$ vim ~/.bashrc
# spark
export SPARK_HOME=/data/spark
export PATH=$SPARK_HOME/bin:$PATH
$ source ~/.bashrc
$ hdfs dfs -mkdir /logs

同步所有spark节点配置文件
在主节点启动master

$ /data/spark/sbin/start-all.sh

在备节点master

/data/spark/sbin/start-master.sh

测试

$ spark-shell --master spark://192.168.233.65:7077 --executor-memory 500m --total-executor-cores 1
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
