Systems and methods for tying token validity to a task executed in a computing system

A server comprising:

• a processor;
• a memory;
• and
• at least one network interface;
• wherein the at least one network interface is to receive a request for a data access token from a computing node, wherein the data access token is a token required to access data stored in a data storage system, and the data stored in the data storage system is required for a task scheduled for execution on the computing node;
• wherein the processor is to:
• verify a digital signature associated with the request for the data access token, and extract a task identifier (ID) that identifies the task from the request for the data access token;
• wherein the at least one network interface is further to:
• transmit a message to a computing device, the message including the task ID and the message querying whether the task identified by the task ID is still being executed by the computing node;
• receive a response from the computing device, the response indicating that the task identified by the task ID is still being executed by the computing node;
• subsequent to receiving the response, send the data access token to the computing node for use by the computing node to access the data from the data storage system during execution of the task by the computing node.

A computer-readable medium having stored thereon computer-executable instructions that, when executed by at least one processor, cause the at least one processor to perform operations comprising:

• receiving a request for a data access token from a computing node, wherein the data access token is a token required to access data stored in a data storage system, and the data stored in the data storage system is required for a task scheduled for execution on the computing node;
• verifying a digital signature associated with the request for the data access token;
• extracting a task identifier (ID) that identifies the task from the request for the data access token;
• transmitting a message to a computing device, the message including the task ID and the message querying whether the task identified by the task ID is still being executed by the computing node;
• receiving a response from the computing device, the response indicating that the task identified by the task ID is still being executed by the computing node;
• subsequent to receiving the response, sending the data access token to the computing node for use by the computing node to access the data from the data storage system during execution of the task by the computing node.
