Sparkj2.X遇到的一个BUG

Posted 2021-01-04 zhaojinyan

spark安装目录下执行start-all.sh后：

[[email protected] spark]$ sbin/start-all.sh
starting org.apache.spark.deploy.master.Master, logging to /home/zdwy/cdh5.9/spark/logs/spark-zdwy-org.apache.spark.deploy.master.Master-1-master.out

解决方案：

在spark-env.sh中加入：

export SPARK_DIST_CLASSPATH=$(/home/zdwy/cdh5.9/hadoop/bin/hadoop classpath)    这里的/home/zdwy/cdh5.9/hadoop/bin/hadoop是我的hadoop的安装目录
