Hello, Partition map exchange is a cluster-wide operation that needs to be finished before cluster becomes operational on a updated topology in your case. It was triggered by node leaving cluster prior to start of the current one.
To find out the reason why it hangs please provide logs from nodes mentioned in partition map exchange diagnostic message: Coordinator node: /Exchange future waiting for coordinator response [crd=09007637-a72e-4a68-940a-10392309eb64../ Node that failed to communicate exchange message: /remaining=[1943a94c-caa2-4082-a04b-a06913489a60../ You can find them in your work directory igniteWorkDir=H:\apache-ignite-fabric-2.4.0-bin\work under log subdirectory, they should be named by default as ignite-09007637.log and ignite-1943a94c.log or you might just grep for locNodeId=xxxx and find the necessary files.
