Hi, I've been trying to run the provided KMeans example on a 16 node cluster. I was testing with 2 Task Managers (TM) per node because each node has 2 sockets (CPUs). A socket contains 12 cores, so I've set the number of slots per TM as 12.The total parallelism is 384 (12 slots x 2 TMs x 16 nodes).
However, Flink TMs keep failing time to time causing KMeans to fail. The only explanation I could find from logs is that TMs unregister from Job Manager. I've increased Akka timeout to 1000s as well. Any suggestions on this? The data sizes I tried were 10k points, 250k points, and 1mil points. Number of centers were 100 to 1000. None of these sizes completed.
