spark2-submit抛出了java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataInputStream
spark2-submit抛出了java.lang.NoClassDefFoundError: org/apache/hadoop/fs/FSDataInputStream
提问于 2017-01-05 07:42:26
我在安装spark 2.0.0后运行spark2-submit时遇到以下错误。
有人知道为什么它不能指向hadoop jar文件吗？当我在spark2-submit中'echo $HADOOP_HOME‘时，它会显示正确的HADOOP_HOME路径。

尝试将HADOOP_HOME/share/hadoop中的jars添加到CLASSPATH。例如，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页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
