Andrey Zagrebin closed FLINK-5791.
----------------------------------
    Resolution: Abandoned

The ticket looks abandoned. I am closing it.

Different slot assignment strategies can be still useful and this is possible now with the pluggable SlotManager. This can be also actual for declarative resource management.

Please, reopen this issue or other issues for custom slot assignment strategies in future.

> In flip6, for yarn mode, it request containers from yarn according to the resource profile in slot requests. And when slots come back after container starting up, we should supporting an optimal matching based slot manager which can assign the slot to the request whose resource profile closest to it. This could reduce resource waste and avoid OOM.
