secondarynamenode异常
2014-08-26 22:06:12,793 ERROR org.apache.hadoop.hdfs.server.namenode.SecondaryNameNode: Exception in doCheckpoint java.io.IOException: Inconsistent checkpoint fields.

原因:
hdfs-site.xml:
<name>dfs.http.address</name>
<value>{your_namenode_ip}:50070</value>
文件中此属性没有配置,second NameNode 无法从NameNode 获取数据。(HTTP的方式获取数据)
此时second NameNode 节点下 :{hadoop.tmp.di}/dfs/namesecondary/current/ 目录下的数据为空
因为无法完成和NameNode 节点之间的数据同步。
