Example 1 with NettySender

use of org.apache.ignite.internal.network.netty.NettySender in project ignite-3 by apache.

the class ItRecoveryHandshakeTest method testHandshakeWithMultipleClients.

/**
 * Tests that one server can handle multiple incoming connections and perform the handshake operation successfully.
 *
 * @throws Exception If failed.
 */

Example 2 with NettySender

use of org.apache.ignite.internal.network.netty.NettySender in project ignite-3 by apache.

the class ItRecoveryHandshakeTest method testHandshakeFailsOnServerWhenClientResponded.

/**

 * server will then close a connection and the client should get the "connection closed event".
 *
 * @throws Exception If failed.
