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. Diffs ----- hadoop/mesos/src/java/org/apache/hadoop/mapred/MesosScheduler.java c5a63bc7a172c44cc11d6bdd6b2eb4bc3df35cb7 Diff: https://reviews.apache.org/r/11976/diff/ Testing ------- make check && make hadoop Thanks, Brenden Matthews
