Question

安装spark 2.0.0后运行spark2-submit时出现以下错误。

有谁知道为什么它无法指向hadoop jar文件？当我在spark2中提及echo $HADOOP_HOME时，会显示正确的HADOOP_HOME路径。

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

spark2-submit抛出java.lang.NoClassDefFoundError：org / apache / hadoop / fs / FSDataInputStream
