CDH 安装后启动报权限错误

OS: RHEL7

CDH:5.10.1

  安装完成后，出现了启动错误。都是因为权限问题引起的。各目录的权限如下：

$ ls -l /var/lib/ |grep hadoop
drwxr-xr-x  5 hdfs         hdfs         4096 Sep  1 13:54 hadoop-hdfs
drwxr-xr-x  2 httpfs       httpfs         75 Jul  7 14:50 hadoop-httpfs
drwxr-xr-x  2 kms          kms            59 Jul  7 14:50 hadoop-kms
drwxr-xr-x  2 mapred       mapred         75 Jul  7 14:50 hadoop-mapreduce
drwxr-xr-x  4 yarn         yarn          130 Jul 10 10:18 hadoop-yarn

解决方法：

    1. chown $path

     2. chmod 755  $path
