> Key: FLINK-7219
> URL: https://issues.apache.org/jira/browse/FLINK-7219
> Project: Flink
> Issue Type: Bug
> Components: JobManager
> Affects Versions: 1.3.1
> Reporter: Sihua Zhou
> Assignee: Sihua Zhou
>
> This is second subtask of issue
> [FLINK-7153|https://issues.apache.org/jira/browse/FLINK-7153?filter=-2].
> Current allocate strategy can't allocate the slot optimize. Here is the test
> case:
> {code}
> JobVertex v1 = new JobVertex("v1", jid1);
> JobVertex v2 = new JobVertex("v2", jid2);
> SlotSharingGroup group = new SlotSharingGroup();
> v1.setSlotSharingGroup(group);
> v2.setSlotSharingGroup(group);
> v1.setParallelism(2);
> v2.setParallelism(4);
> v1.setInvokableClass(BatchTask.class);
> v2.setInvokableClass(BatchTask.class);
> v2.connectNewDataSetAsInput(v1, DistributionPattern.POINTWISE,
> ResultPartitionType.PIPELINED_BOUNDED);
> {code}
> Currently, after allocate for v1,v2, we got a local partition and three
> remote partition. But actually, it should be 2 local partition and 2 remote
> partition.
> The causes of the above problems is becuase that the current allocate
> strategy is allocate the resource for execution one by one(if the execution
> can allocate from SlotGroup than get it, Otherwise ask for a new one for it).
