apache-spark - 分别配置Spark和Hadoop(哪个版本将hadoop与spark配合使用)

Question

我正在尝试使用hadoop 3.1.2配置spark 2.4.4，我已经成功安装了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)

但是当我开始 Spark 壳

如何检查带有Spark的hadoop的哪个版本

Answer 1

Spark使用HADOOP_HOME并从那里加载类路径，因此您下载的版本是它将使用的版本

请注意，Spark尚未完全支持Hadoop3。
