Subject Re: Please reply if you use Mesos fine grained mode

we use fine-grained mode. coarse-grained mode keeps JVMs around which often
leads to OOMs, which in turn kill the entire executor, causing entire
stages to be retried. In fine-grained mode, only the task fails and
subsequently gets retried without taking out an entire stage or worse.
