To implement the SUBMIT_JOB RPC and the required queueing behavior in a MapReduce coordinator, follow these steps: Job Tracking: Job Queue: Define a cleanup function for job_metadata_t: This implementation should satisfy the requirements for job submission, queueing, and task assignment while being simple to extend and debug. Please share the content of your rpc.x file so I can help you integrate the provided definitions into your implementation and ensure your SUBMIT_JOB RPC works as expected. Your rpc.x file defines the necessary RPCs and data structures for a MapReduce coordinator. Here's how you can integrate it into your SUBMIT_JOB RPC implementation and start building the coordinator logic. submit_job_request: poll_job_reply: get_task_reply: finish_task_request: RPC Definitions: The data structures from my earlier response are still valid, but we now integrate them with the provided protocol. Handles the POLL_JOB RPC, allowing clients to query the status of their jobs. Handles th
