> Once the shut down process is initiated, impalad would stop accepting any new connections or queries. This makes it difficult if a user wants to shut down impalad across a cluster via the shutdown command. For eg. the user would need to make sure to send the command to all executors before sending them to the coordinators. Adding a mechanism to initiate the graceful shutdown process with a large deadline by sending a SIGQUIT to the impalad process would make cluster management simpler.
