[jira] [Updated] (IGNITE-13094) java.lang.ClassNotFoundException:
ch.qos.logback for distributed compute
[ https://issues.apache.org/jira/browse/IGNITE-13094?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
AK47Sonic updated IGNITE-13094:
-------------------------------
Description:
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?

> 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?
