Tzu-Li (Gordon) Tai commented on FLINK-13476:
---------------------------------------------

Since this is a blocker for 1.9.0, we should remove the 1.10.0 tag as fix version. I will remove it.

> With FLINK-12615 we removed that partitions are being explicitly released from the JM if an {{Execution}} which is in state {{FINISHED}} or {{FAILED}} is being cancelled. In order to not have resource leak when using pipelined result partitions whose consumers fail before start consuming, we should re-introduce the deleted else branch (removed via 408f6b67aefaccfc76708b2d4772eb7f0a8fd984).
> Once we properly wait that a {{Task}} does not finish until its produced results have been either persisted or sent to a consumer, then we should be able to remove this branch again.
