[jira] [Commented] (IGNITE-13719) Thin client silently closes channel after inactivity

["Aleksey Plekhanov (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-13719?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17234543#comment-17234543 ] 

Aleksey Plekhanov commented on IGNITE-13719:
--------------------------------------------

[~ptupitsyn], I don't think it's blocked by IGNITE-13496, I think it can be relatively easy fixed by waiting for future {{pendingReq}} with timeout in {{TcpClientChannel#receive}} instead of timeout on socket. Also, patch can be included to 2.9.1 scope.

> The following code works fine with ignite-core 2.8.0, but fails with 2.9.0 (see the exception below). It looks like timeout is applied to client receiver thread. When it's not used for a while it gets closed silently. 
> {code:java}
> public class IgniteDemo
> {
>     public static final int TIMEOUT = 1000;
>     public static void main(String[] args) throws InterruptedException
>     {
>         new IgniteDemo().run();
>     }
>     public void run() throws InterruptedException
>     {
>         final Ignite igniteServer = Ignition.start();
>         final ClientConfiguration cfg = new ClientConfiguration().setAddresses("127.0.0.1:10800");
>         cfg.setTimeout(TIMEOUT);
>         final IgniteClient igniteClient = Ignition.startClient(cfg);
>         final ClientCache<Object, Object> cache = igniteClient.getOrCreateCache("test");
>         Thread.sleep(TIMEOUT);
>         cache.put(1, 1);
>         Thread.sleep(TIMEOUT);
>         cache.put(2, 2);
