> Detecting and stopping unresponsive nodes during Partition Map Exchange

> During PME process coordinator (1) gathers local partition maps from all
> nodes and (2) sends calculated full partition map back to all nodes in the
> topology.
> However if one or more nodes fail to send local information on step 1 for any
> reason, PME process hangs blocking all operations. The only solution will be
> to manually identify and stop nodes which failed to send info to coordinator.
> This should be done by coordinator itself: in case it didn't receive in time
> local partition maps from any nodes, it should check that stopping these
> nodes won't lead to data loss and then stop them forcibly.
