Hadoop 2.7.3 Java运行时错误-未找到core-site.xml

Question

在运行hdfs dfs -mkdir /abc时，我得到以下错误。

Exception in thread "main" java.lang.RuntimeException: core-site.xml not found

我的core-site.xml的路径是/usr/local/hadoop/etc/hadoop/core-site.xml。

如何修复此错误？

Answer 1

您可以尝试在~/.bash_profile中或在脚本的开头设置以下变量。

export HADOOP_CONF_DIR=**location of your hadoop in local**

就像(/home/hadoop/hadoop-2.7.3/etc/hadoop )
