# Dynamic Resource Allocation with Mesos
-Mesos supports dynamic allocation only with coarse grain mode, which can
resize the number of executors based on statistics
-of the application. While dynamic allocation supports both scaling up and
scaling down the number of executors, the coarse grain scheduler only supports
scaling down
-since it is already designed to run one executor per slave with the
configured amount of resources. However, after scaling down the number of
executors the coarse grain scheduler
-can scale back up to the same amount of executors when Spark signals more
executors are needed.

-Users that like to utilize this feature should launch the Mesos Shuffle
Service that
-provides shuffle data cleanup functionality on top of the Shuffle Service
since Mesos doesn't yet support notifying another framework's

provided sbin/start-mesos-shuffle-service.sh and
sbin/stop-mesos-shuffle-service.sh
-scripts accordingly.
