[jira] [Commented] (IGNITE-1267) JobStealingCollisionSpi never
sends jobs to a node that joined after task was executed
[ https://issues.apache.org/jira/browse/IGNITE-1267?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14727253#comment-14727253 ]
Yakov Zhdanov commented on IGNITE-1267:
---------------------------------------
I think the same is valid for simple job failover when any other collision is used or collision is disabled. I suggest to also fix - newly joined nodes should participate in task topology for failover if they satisfy topology predicate.

> Essentially, {{JobStealingCollisionSpi}} always skips jobs that are not in task topology (see line 713). Task topology is static and created when task is executed, so newly joined node can't steal jobs. I think it should be able to do this if it satisfies initial cluster group predicate.
