DATA MANAGEMENT IN A MULTI-TENANT DISTRIBUTIVE ENVIRONMENT
First Claim
1. A method for managing tenant data in a multi-tenant distributed environment, the method comprising:
- receiving, from a tenant, a request for resources, the request for resources intended for processing a job;
in response to the request, providing a virtual metadata server specific to the tenant, the virtual metadata server providing an independent logical file system namespace for the tenant; and
registering the virtual metadata server with a job manager, the job manager configured to access data related to the tenant via the virtual metadata server.

Abstract
The present invention relates to a method and apparatus for data management in multi-tenant distributive environment. According to the embodiments of the present invention, a tenant-specific virtual metadata server may be created and registered with a task manager in a job processing system. The virtual metadata server provides a tenant-specific logical file system namespace. Any access to tenant data will be performed via the virtual metadata server. In other words, such virtual metadata server acts as an interface between a tenant terminal and an entity file system. In this way, it may effectively realize isolation of tenant data and enhance data security. Moreover, by using a virtual metadata server rather than physically isolating user data, the embodiments of the present invention may guarantee the efficiency of data sharing while improving the data security.

20. An apparatus for managing distributed job processing, the apparatus comprising a managing unit configured to register a virtual metadata server specific to a tenant, the virtual metadata server providing an independent logical file system namespace for the tenant;
-
during processing a job of the tenant, access data related to the tenant via the virtual metadata server; receiving, from the tenant, a request for processing a job;
in response to the request, request a memory location of the data related to the job with the virtual metadata server, and receiving, from the virtual metadata server, an actual address of the data related to the job in a global file system namespace of a distributed file system that stores tenant data, the actual address representing the memory location, and assign an execution node for executing the job of the tenant based on the actual address.
