Can ES node rejoin the cluster after network failure?


(Weiwei Wang) #1

I found that if the network failure happens, the es nodes who lost the
master become master itself and then never come back.

I want the lost nodes can come back, otherwise i will lost some index
data and have to restart the lost nodes.

?

Hi,

This is quite broad topic (and I am not expert in it). May be you
should consider using shared gateway or increase number of index shard
replicas. By the way this topic has been discussed on ML many times,
usually they refer to network partitioning or brain split problems.
For example check the following thread:

Lukas
