Abstract
Some examples include a plurality of nodes configured to execute map-reduce jobs by enabling tasks to share processing slots with other tasks. As one example, a job tracker may compare a task profile for a received task with one or more task profiles for one or more respective tasks already assigned for execution on the processing slots of one or more worker nodes. Based at least in part on the comparing, the job tracker may select a particular one of already assigned tasks to be executed concurrently with the received task on a slot. In addition, the job tracker may determine one or more expected future tasks based at least in part on one or more ongoing workflows of map-reduce jobs. The selection of the already assigned task to be executed concurrently with the received task may also be based in part on the expected future tasks.
