Miron Aseev updated IGNITE-2405:
--------------------------------
Attachment: log.out
Did a small fix. There is actually no need to fully copy the class in order to
change its hidden behaviour. Did the trick by placing my custom TcpDiscoverySpi
class in the same package and made it extend the real TcpDiscoverySpi. By doing
so, I was able to override the required method which has the default access
modifier.

> Key: IGNITE-2405
> URL: https://issues.apache.org/jira/browse/IGNITE-2405
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.5.0.final
> Reporter: Miron Aseev
> Labels: community, newbie
> Attachments: log.out, log.out, log.out, log.out, log.out
>
>
> It seems that Apache Ignite runs an infinite loop if it can't connect to the
> resolved hostname.
> For example, if you specify the hostname of the local machine as an address
> for the TCPSpi, then Apache Ignite resolves it
> [here|https://github.com/apache/ignite/blob/b3d347e35a254928fd1c4a0473f1b17d642c72f3/modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/ServerImpl.java#L915].
>
> But after that, for some reasons, it fails to connect to the resolved address
> [here|https://github.com/apache/ignite/blob/b3d347e35a254928fd1c4a0473f1b17d642c72f3/modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/ServerImpl.java#L925].
>
> As a result, the control flow goes to the catch block where the exception is
> logged (It's an IgniteSpiException. It seems it can't get access to the host
> according to the exception message - "Network operation timed out. Increase
> 'failureDetectionTimeout' configuration property
> [failureDetectionTimeout=10000]").
> In the end, we get an infinite loop.
> On the other hand, If I set an ip address (127.0.0.1) instead of the
> hostname, Ignite gets an empty list
> [here|https://github.com/apache/ignite/blob/b3d347e35a254928fd1c4a0473f1b17d642c72f3/modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/ServerImpl.java#L915]
> and the control flow breaks the loop
> [here|https://github.com/apache/ignite/blob/b3d347e35a254928fd1c4a0473f1b17d642c72f3/modules/core/src/main/java/org/apache/ignite/spi/discovery/tcp/ServerImpl.java#L918]
> and goes forward.
