> In the case that a job allocates a few slots first and after a period
> allocates some other slots. The YarnResourceManager seems to receive and
> ignore the latter slot requests.
> To produce this issue, we can create a job with 2 vertices in different
> shared groups, as shown below:
> !17_37_05__07_12_2019.jpg|width=433,height=127!
> Slot allocation for map2 vertex happens after the source vertex acquires
> slots to decide its location, thus to meet the input constraints.
> YarnResourceManager can receive slot requests for map2, but seems not to
> handle it and the job will hang there waiting for resources.
> In my observation, this issue does not happen on Flink(Version: 1.9-SNAPSHOT,
> Rev:3bc322a, Date:26.06.2019 @ 17:28:51 CST). It should be a new issue after
> that.
