安装 spark 2.0.0 后运行 spark2-submit 时出现以下错误。

有谁知道为什么它不能指向 hadoop jar 文件？当我在 spark2-submit 中“echo $HADOOP_HOME”时，它显示了正确的HADOOP_HOME 路径。

【解决方案1】：

尝试将 HADOOP_HOME/share/hadoop 中的 jar 添加到 CLASSPATH。比如我在/etc/profile中添加了CLASSPATH，我的hadoop版本是2.7.2

export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-client-core-2.7.2.jar:$HADOOP_HOME/share/hadoop/common/hadoop-common-2.7.2.jar:$HADOOP_HOME/share/hadoop/common/lib/commons-cli-1.2.jar:$CLASSPATH
