Ivan Pavlukhin commented on IGNITE-13094:
-----------------------------------------
Hi [~AK47Sonic],
I guess that server startup procedure matters here (binary distribution in your
case and Java code in my). And it turns out that Ilya caught the cause. But why
log classes need to be loaded remotely in the described case is not clear for
me (it still might be a technical detail I do not understand).
> java.lang.ClassNotFoundException: ch.qos.logback for distributed compute
> ------------------------------------------------------------------------

> Key: IGNITE-13094
> URL: https://issues.apache.org/jira/browse/IGNITE-13094
> Project: Ignite
> Issue Type: Bug
> Components: compute
> Affects Versions: 2.8.1
> Environment: Ignite 2.8.0
> Spring Boot 2.1.0.RELEASE
> Java 1.8
> Reporter: AK47Sonic
> Assignee: Ilya Kasnacheev
> Priority: Major
>
> I try to use spring boot (2.1.0.RELEASE) to run ignite.compute. As spring
> boot + lombok use logback as default, the following codes always throw
> exceptions (2020-05-28 07:00:48.979 WARN 8460 --- [ p2p-#49]
> o.a.i.i.m.d.GridDeploymentCommunication : Failed to resolve class:
> ch.qos.logback). The result (28) could be returned. Seems we see log4j and
> log4j2 on official website. I try to use log4j2 to replace logback. And it
> works fine. Does ignite support logback for distributed compute? Or It is
> just a bug?
