Is process cluster event timeout value configurable and how if yes?

I got ProcessClusterEventTimeoutException when create/delete index, default value is 30s. Is this configurable and how to config it?

org.elasticsearch.cluster.metadata.ProcessClusterEventTimeoutException: failed to process cluster event (delete-index [[xxx-indexname]]) within 30s

Yes, you can pass a different timeout on a request-by-request basis: DELETE /my-index?timeout=60s&master_timeout=60s. However, if it's exceeding the default 30-second timeout then I suspect there's something wrong with your cluster, particularly since deleting an index is an URGENT-priority task which should be happening well within 30 seconds.
