处理方式：
- [root@master bin]# cd /opt/data/hadoop/hdfs/name/current/
- [root@master current]# ls
- edits fsimage fstime VERSION
- [root@master current]# ll
- total 32
- -rw-r--r-- 1 root root 4 Aug 31 10:07 edits
- -rw-r--r-- 1 root root 1753 Aug 31 10:07 fsimage
- -rw-r--r-- 1 root root 8 Aug 31 10:07 fstime
- -rw-r--r-- 1 root root 101 Aug 31 10:07 VERSION
- [root@master current]# pwd
- /opt/data/hadoop/hdfs/name/current
- [root@master current]# chown hadoop:hadoop -R /opt/data/hadoop/hdfs/name/current/
切换到hadoop用户，start-all.sh 问题解决。
- [hadoop@master bin]$ cd /opt/modules/hadoop/hadoop-0.21.0/bin
- [hadoop@master bin]$ ls
- hadoop hadoop-daemons.sh mapred slaves.sh start-dfs.sh stop-balancer.sh
- hadoop-config.sh hdfs mapred-config.sh start-all.sh start-mapred.sh stop-dfs.sh
- hadoop-daemon.sh hdfs-config.sh rcc start-balancer.sh stop-all.sh stop-mapred.sh
- [hadoop@master bin]$ sh start-all.sh
- This script is Deprecated. Instead use start-dfs.sh and start-mapred.sh
- starting namenode, logging to /opt/modules/hadoop/hadoop-0.21.0/bin/../logs/hadoop-hadoop-namenode-master.out
