hadoop的namenode起不来，Directory /tmp/hadoop-hadoop/dfs/name is in an inconsistent state

hadoop第一次起启动时没有问题，但机子重启之后就会出现

irectory /tmp/hadoop-hadoop/dfs/name does not exist. 2013-02-02 16:49:29,297 ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: FSNamesystem initialization failed. org.apache.hadoop.hdfs.server.common.InconsistentFSStateException: Directory /tmp/hadoop-hadoop/dfs/name

/tmp/hadoop-hadoop/dfs/name是一个临时的文件夹，系统每次重启时都会进行删除，在配置文件中进行修改就可。

conf/core-site.xml

<property>
<name>hadoop.tmp.dir</name>
<value>/home/javoft/Documents/hadoop/hadoop-${user.name}</value>
<description>A base for other temporary directories.</description>
</property>

<value>的值根据自己的情况调整。

重启hadoop

bin/stop-all.sh

bin/hadoop namenode -format

bin/start-all.sh

问题解决。namenode已经可以启动了。
