Hello Pavel, Thanks for the explanation, it's been great help.
Can you take a guess why PME has performed a long time due to communication issues between server nodes? >From the logs, the "no route to host" exception happened because server can't connect to client's ports. But I didn't see any logs indicating the network issues between server nodes. I tested connectivity of communication SPI ports(47100 in this case) and discovery SPI ports(49500 in this case) between server nodes, it's all good. And on client(spark executor) side, there's no exception log when PME takes a long time to finish. It will hang forever.
