[hadoop@dns app]$

之所以出现

stackOverflowerError

，是因为java调用堆栈已经增长，并且运行JVM中没有更多内存来容纳更多的调用堆栈细节

请仔细查看Java错误堆栈并注意 -有以下两个功能

public static FileContext getFileContext(final URI defaultFsUri, final Configuration aConf)
public static FileContext getFileContext(final Configuration aConf)

在某些情况下，第一个getFileContext调用第二个getFileContext，第二个getFileContext调用第一个getFileContext。这意味着它的递归调用

在您的情况下，

core site.xml

必须包含值为

cluster1

的属性

fs.defaultFS

。相反，它应该是

hdfs://cluster1

。如果将

fs.defaultFS

设置为正确的URL

hdfs://cluster1

在您的示例中，core-site.xml必须包含值为cluster1的属性fs.defaultFS。应该是这样hdfs://cluster1. 如果将fs.defaultFS设置为正确的URL，递归调用将消失hdfs://cluster1.

谢谢，当我用value更改fs.defaultFS时hdfs://cluster1 ，问题已经解决了
