Mine is a three node ES cluster running 2.3.2. I am using REST API's and carrying out bulk indexing. I see this response
{"error":{"root_cause":[{"type":"cluster_block_exception","reason":"blocked by: [SERVICE_UNAVAILABLE/2/no master];"}],"type":"cluster_block_exception","reason":"blocked by: [SERVICE_UNAVAILABLE/2/no master];"},"status":503}
In the post https://discuss.elastic.co/t/503-service-unavailable-2-no-master/64793, one of the member has mentioned that when a node joins master election triggers. Does the master election triggers every time a master eligible node joins or only when no master is present in the cluster currently ?
Also what might be other possible reasons one might encounter this issue
