获得此例外：

    2014-09-06 23:14:04,906 FATAL org.apache.hadoop.hdfs.server.namenode.NameNode:       Exception in namenode join

这是netstat的输出： [hduser @ xyz hadoop] $ netstat -anl | grep 54310

tcp        0      0 10.0.112.61:54310           0.0.0.0:*                   LISTEN

这是/ etc / hosts

127.0.0.1               localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

198.245.16.35 slave

10.0.112.61 master

我在Red Hat Linux上使用hadoop-2.2.0。

在其他地方，我读到在格式化名称节点（http://comments.gmane.org/gmane.comp.java.hadoop.mapreduce.user/7275）时应该运行日志节点。

有人可以澄清一下日志节点的用途吗？任何帮助表示赞赏。
