Master election time during failover


(Kamaljit Pati) #1

Hi all, I am configuring elasticsearch on 3 nodes for my organization. I have a doubt that when one node(server) is down or crashed, then how much time the cluster needs to elect the new master among the remaining 2 nodes. When another node is down, then cluster is inoperable, that i know. Actually i need the time to use elasticsearch efficiently. All the 3 nodes have 32 GB RAM and 4 cores.
