Cluster state is showing yellow. What's the best way to find why it's in yellow state? It has been up and stable so far except when I looked today it shows state turned into yellow. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Yellow means it's got unallocated shards. Install something like elastichq or kopf and you should be able to see why.

I am trying to understand why I should change it? This setting looks like the right setting in most cases. Did you see anything out of ordinary in that log message I pasted?

The logs shows that a node was not contactable and so was removed from the cluster. That could be a load issue on the node, network issues, or something else. Check the logs on the node that disconnected and see what you find. If you leave the defaults, you risk the chance of a split-brain situation, where nodes lose contact with each other and then decide to become a master. This can cause you to end up with multiple masters in multiple clusters, which is not good for data integrity. Setting the min masters means that if a node cannot contact N masters, it will refuse connections.

I didn't quite understand. What I am trying to find is that when default formula of N / 2 + 1 I will always have more master nodes on one side correct? And is my understanding incorrect that the other side that has less master nodes than N /2 + 1 would simply not accept any requests? The only point of increasing this value would be for performance reasons?

Default value for minimum master node is 1. No formula here. It was just an advice.

What I am trying to find is that when default formula of N / 2 + 1 I will always have more master nodes on one side correct? And is my understanding incorrect that the other side that has less master nodes than N /2 + 1 would simply not accept any requests?

To be fair, the default minimum\_master\_node value is -1 (disabled). Problem is, you do not know N when an ES node starts up and uses discovery - it can grow by time 😉 Jörg -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

The formula N+1/2 can not be used by ES as default for minimum\_master\_nodes because for the variable N the value is unknown.
