ExecutorData¶

ExecutorData is a metadata of an executor:

• Executor's RPC Endpoint
• Executor's RpcAddress
• Executor's Host
• Executor's Free Cores
• Executor's Total Cores
• Executor's Log URLs (Map[String, String])
• Executor's Attributes (Map[String, String])
• Executor's Resources Info (Map[String, ExecutorResourceInfo])
• Executor's ResourceProfile ID

ExecutorData is created for every executor registered (when DriverEndpoint is requested to handle a RegisterExecutor message).

ExecutorData is used by CoarseGrainedSchedulerBackend to track registered executors.
