To maximize the use of a cluster's available computing resources, multiple execution plans can be associated to the same cluster and executed in parallel.
- Jobs in the same execution plan are executed in sequence. By default, preceding jobs are executed before new jobs can be submitted and executed.
- If you have enough cluster resources, you can create multiple different execution plans and associate them to the same cluster to run and execute jobs in parallel. Clusters support a maximum of 20 execution plans by default.
- The management and control system currently supports the submission to YARN of multiple execution plans associated to the same cluster. However, if the cluster itself has insufficient resources, it may take some time for jobs in the YARN queue to wait for scheduling.
