[jira] [Commented] (IGNITE-2405) Ignite is blocking the thread in
case it can't connect to the node
[ https://issues.apache.org/jira/browse/IGNITE-2405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15108459#comment-15108459 ]
Vladimir Ershov commented on IGNITE-2405:
-----------------------------------------
Miron,
Thank you for a well formed request and an attached test! I've run this test on my side and it is not reproduced. I've also check the code you've mentioned and here are some thoughts and steps I can suggest to proceed with this issue:
# Before any further reproduction, please check, that there is no any other Ignite nodes in your net, and all java processes for Ignite cluster are terminated.
# Then, please, set DEBUG level for TcpDiscoverySpi and ServerImpl, reproduce this issue and attach all logs including full stack trace for an exception.
Than I can provide you with further assistance.

> Key: IGNITE-2405
> URL: https://issues.apache.org/jira/browse/IGNITE-2405
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.5
> Reporter: Miron Aseev
> Labels: community, newbie
>
> 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 acces 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.
