There is no default segmentation resolver. If there’s a pause, or network glitch, you’ll likely end up with two clusters. > On 28 Sep 2021, at 10:52, 38797715 <38797...@qq.com> wrote: > > No, it's completely the default implementation. > > I understand that if the cluster has only two nodes, no

No, it's completely the default implementation. I understand that if the cluster has only two nodes, node1 (Coordinator) and node2, and if two nodes are disconnected due to long GC, node2 should be shut down due to split brain, but it doesn't seem to be so now. AFAIK, if the cluster is 3 node

My question is, does the current behavior seem to be inconsistent with the default SegmentationPolicy = STOP?

No, a cluster doesn’t need at least three nodes. According to your logs you experienced a “long JVM pause.” If a node stops responding, it gets kicked out of the cluster. It’s likely you need to tune your garbage collection, though there are other possible causes of long pauses too. > On 28 Sep

Does ignite cluster need at least 3 nodes?

Hi team, There is a cluster with 2 server nodes and 1 client node. It can be seen from the attached log that the two server nodes are disconnected from about 20:18:15. However, it is strange that the node with IP 10.97.32.53 did not shut down due to split brain. Instead, it is split into two
