spark.mesos.coarse |
- false |
+ true |
- If set to true , runs over Mesos clusters in
- "coarse-grained" sharing mode,
- where Spark acquires one long-lived Mesos task on each machine instead of one Mesos task per
- Spark task. This gives lower-latency scheduling for short queries, but leaves resources in use
- for the whole duration of the Spark job.
+ If set to true , runs over Mesos clusters in "coarse-grained" sharing mode, where Spark acquires one long-lived Mesos task on each machine.
+ If set to false , runs over Mesos cluster in "fine-grained" sharing mode, where one Mesos task is created per Spark task.
