Summary: Detecting and stopping unresponsive nodes during
Partition Map Exchange
Key: IGNITE-8828
URL: https://issues.apache.org/jira/browse/IGNITE-8828
Project: Ignite
Issue Type: Improvement
Reporter: Sergey Chugunov
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.
