在我的Hadoop2.6.5 HA中，当我使用sqoop 1.4.6从mysql数据导入数据时，出现以下错误。
操作系统:Centos6.5bit
有人面对同样的问题吗？
如果任何地方我想念它？

最佳答案
之所以发生StackOverFlowError，是因为Java调用栈已经增长，并且在运行JVM中没有更多的内存来容纳更多的调用栈详细信息。
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)
在某些条件下，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fs.defaultFS的cluster1属性。相反，它应该是hdfs://cluster1。如果将fs.defaultFS设置为正确的URL hdfs://cluster1，则递归调用将消失。
关于java - 我的hadoop2.6.5 HA，当从mysql导入数据时，运行错误java.lang.StackOverflowError，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/45997907/
