To reply, visit: https://reviews.apache.org/r/11976/ ----------------------------------------------------------- Review request for mesos. Description ------- Allow specification of mininum slot count. To ensure Hadoop jobs begin promptly, we can specify a minimum number of 'hot slots' to be available for use. This addresses the TaskTracker spin up delay that exists with Hadoop on Mesos. This can be a nuisance with lower latency applications, such as ad-hoc Hive queries.
