我在群集设置中使用Hadoop 2.2.0并且我反复收到以下错误，异常在文件/opt/dev/hadoop/2.2.0/logs/hadoop-deploy-secondarynamenode-olympus.log下的名称节点olympus中生成，例如

有人可以在这里建议什么是错的吗？

Answer 1

我遇到了同样的错误，当我删除[hadoop临时目录] / dfs / namesecondary目录时，它就出现了。对我来说[hadoop临时目录]是core-site.xml中hadoop.tmp.dir的值

Answer 2

我们需要先停止hadoop服务，然后删除tmp辅助namenode目录（hadoop.tmp.dir将告诉辅助namenode数据目录的路径）。在此之后，再次启动服务，问题将得到解决。

错误org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode：doCheckpoint中的异常
