Generic options supported are:
-conf <configuration file>        specify an application configuration file
-D <property=value>               define a value for a given property
-fs <file:///|hdfs://namenode:port> specify default filesystem URL to use, overrides 'fs.defaultFS' property from configurations.
-jt <local|resourcemanager:port>  specify a ResourceManager
-files <file1,...>                specify a comma-separated list of files to be copied to the map reduce cluster
-libjars <jar1,...>               specify a comma-separated list of jar files to be included in the classpath
-archives <archive1,...>          specify a comma-separated list of archives to be unarchived on the compute machines

The general command line syntax is:
command [genericOptions] [commandOptions]

# 查看当前hdfs里面 / 下有的子目录
hdfs dfs -ls /

# 创建自己需要的目录
hdfs dfs -mkdir -p /dolphinscheduler

# 查看创建（存在）目录的权限
hdfs dfs -getfacl /dolphinscheduler

# file: /dolphinscheduler
# owner: root
# group: supergroup
user::rwx
group::r-x
mask::rwx
other::r-x

此时filepath只有名为root的owner有权限。

hdfs dfs -setfacl -R -m user:dolphinscheduler:rwx /dolphinscheduler
　　返回结果如下
