Introduction

A user is a human agent (end-user) who uses QueryIO services.
There are two types of users in QueryIO:

• Admin User

Admin user has all the administration privileges. He is responsible for managing HDFS cluster, QueryIO services and users. These are some of the operations that only a user with administrator privileges can perform:

• Manage cluster nodes.
• Manage QueryIO services.
• Add / remove users. Manage user privileges.
• Manage user groups.
• Access all the files present on the HDFS cluster irrespective of their permissions.
• Non-admin User

A non admin user cannot perform any cluster mangement operations. However, he can read / write files on HDFS in the directories that he has permissions for. He can also share his files with other users by changing file permissions. He can also execute map-reduce jobs, perform analytics operations and view reports.
