原因：

使用root用户运行spark代码

解决方法：使用非管理员账户运行spark即可

[userone@localhost bin]$ ./add-user.sh What type of user do you wish to add? a) Management User (mgmt-users.properties) b) Application User (application-users.properties) (a): b Enter the details of the new user to add. Realm (ApplicationRealm) : ApplicationRealm ---->> Careful Here . You need to type this or leave it blank . I filled an incorrect value here and things went wrong from there . Username : testuser Password : testpassword Re-enter Password : testpassword What roles do you want this user to belong to? (Please enter a comma separated list, or leave blank for none) : testrole About to add user 'testuser' for realm 'ApplicationRealm' Is this correct yes/no? yes Added user 'testuser' to file '/home/userone/jboss-as-7.1.0.Final/standalone/configuration/application-users.properties' Added user 'testuser' to file '/home/userone/jboss-as-7.1.0.Final/domain/configuration/application-users.properties' Added user 'testuser' with roles testrole to file '/home/userone/jboss-as-7.1.0.Final/standalone/configuration/application-roles.properties' Added user 'testuser' with roles testrole to file '/home/userone/jboss-as-7.1.0.Final/domain/configuration/application-roles.properties'
