错误org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode：doCheckpoint中的异常 [英] ERROR org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Exception in doCheckpoint

问题描述

我在集群设置中使用Hadoop 2.2.0，并且重复出现以下错误，异常在名为节点olympus的文件 /opt/dev/hadoop/2.2.0下生成/logs/hadoop-deploy-secondarynamenode-olympus.log eg

I'm using Hadoop 2.2.0 in a Cluster setup and I repeatedly get the following error, the Exception is produced in the name node olympus under file /opt/dev/hadoop/2.2.0/logs/hadoop-deploy-secondarynamenode-olympus.log e.g.

任何人都可以建议这里有什么问题吗？

Can anyone advice what's wrong here?

推荐答案

我有同样的错误， [hadoop临时目录] / dfs / namesecondary目录。
对我来说[hadoop临时目录]是core-site.xml中的hadoop.tmp.dir的值。

I had the same error and it went when I deleted the [hadoop temporary directory]/dfs/namesecondary directory. For me [hadoop temporary directory] is the value of hadoop.tmp.dir in core-site.xml
