Class Sniffer

java.lang.Object

org.elasticsearch.client.sniff.Sniffer

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

public class Sniffer
extends java.lang.Object
implements java.io.Closeable

Class responsible for sniffing nodes from some source (default is elasticsearch itself) and setting them to a provided instance of RestClient. Must be created via SnifferBuilder, which allows to set all of the different options or rely on defaults. A background task fetches the nodes through the HostsSniffer and sets them to the RestClient instance. It is possible to perform sniffing on failure by creating a SniffOnFailureListener and providing it as an argument to RestClientBuilder.setFailureListener(RestClient.FailureListener). The Sniffer implementation needs to be lazily set to the previously created SniffOnFailureListener through SniffOnFailureListener.setSniffer(Sniffer).
