> Key: IGNITE-14671
> URL: https://issues.apache.org/jira/browse/IGNITE-14671
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.11
> Reporter: Ilya Shishkov
> Assignee: Ilya Shishkov
> Priority: Trivial
> Labels: iep-43
> Fix For: 2.11
>
> Attachments: testClusterSnapshotCheckOtherCluster_fix.patch,
> testClusterSnapshotCheckOtherCluster_printCount.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> To reproduce failure, run it several times, for example, set up IDE to run
> test with 'repeat until failure' option. Then you will get an assertion error:
> {code:java}
> java.lang.AssertionError: Number of jobs must be equal to the cluster size
> (except local node): [a2844419-3081-432a-b611-c4f891900005]

> With applied patch [1] exception would be as follows:

> java.lang.AssertionError: Number of jobs must be equal to the cluster size
