The configurations on the two nodes are almost the same except the ** node.name**.
The first question is very strange. I I run the same config on another cluster of two nodes and after I index data, the state of the cluster is green. I have no idea why this happened......Is there something I ignore? I want to know how ES allocates nodes. Is there some reference? I googled but couldn't find it.
