Till Rohrmann commented on FLINK-5857:
--------------------------------------
Hi [~tiemsn], the new {{SlotManager}} implementation (see FLINK-5810)
introduces a timeout for idling {{TaskExecutors}}. Once a {{TaskExecutor}}
times out, the {{TaskExecutor}} is removed from the {{SlotManager}} and the
{{ResourceManager}} is informed about it (e.g. to release the container).
Thus, I think we can close this issue. What do you think?
