我正在尝试用hadoop 3.1.2配置spark 2.4.4，我已经成功地安装了hadoop-3.1.2.tar.gz和spark-2.4.4-bin-without-hadoop.tgz，并且我已经构建了conf/spark-env.sh文件

export JAVA_HOME=/opt/jdk8u202-b08
export HADOOP_HOME=/home/hadoop/hadoop
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop
export SPARK_HOME=/usr/local/spark
export SPARK_DIST_CLASSPATH=$HADOOP_HOME/etc/hadoop
export SPARK_DIST_CLASSPATH=($HADOOP_HOME/bin/hadoop classpath)

但当我开始使用spark shell时
