hadoop 启动时候出现权限不够问题

[tech05 @wz conf]$ start-all.sh
starting namenode, logging to /opt/software/hadoop/libexec/../logs/hadoop-tech05-namenode-wz.out
/opt/software/hadoop/bin/hadoop-daemon.sh: line 137: /tmp/hadoop-tech05-namenode.pid: 权限不够
localhost: starting datanode, logging to /opt/software/hadoop/libexec/../logs/hadoop-tech05-datanode-wz.out
localhost: starting secondarynamenode, logging to /opt/software/hadoop/libexec/../logs/hadoop-tech05-secondarynamenode-wz.out
starting jobtracker, logging to /opt/software/hadoop/libexec/../logs/hadoop-tech05-jobtracker-wz.out
/opt/software/hadoop/bin/hadoop-daemon.sh: line 137: /tmp/hadoop-tech05-jobtracker.pid: 权限不够
localhost: starting tasktracker, logging to /opt/software/hadoop/libexec/../logs/
但是用jps可以查看五个进程启动了

然后用网页打开hdfs系统进入到/usr/hadoop/tmp/mapred/system 下面会出现

org.apache.hadoop.security.AccessControlException: Permission denied: user=webuser, access=READ_EXECUTE, inode="system":tech05:supergroup:rwx------

这个正常么

是不是hadoop安装包下面的东西都得给他们进行 777 权限操作 要不就会出现不允许的操作
