Today the discovery phase has a short 1-second timeout for handshaking with a remote node after connecting, which allows it to quickly move on and retry in the case of connecting to something that doesn't respond straight away (e.g. it isn't an Elasticsearch node). This short timeout was necessary when the component was first developed because each connection attempt would block a thread. Since #42636 the connection attempt is now nonblocking so we can apply a more relaxed timeout. If transport security is enabled then our handshake timeout applies to the TLS handshake followed by the Elasticsearch handshake. If the TLS handshake alone takes over a second then the whole handshake times out with a `ConnectTransportException`, but this does not tell us which of the two individual handshakes took so long. TLS handshakes have their own 10-second timeout, which if reached yields a `SslHandshakeTimeoutException` that allows us to distinguish a problem at the TLS level from one at the Elasticsearch level. Therefore this commit extends the discovery probe timeouts. |
