Subject [jira] [Commented] (IGNITE-8783) Failover tests periodically cause hanging of the whole Data Structures suite on TC
Date Wed, 18 Jul 2018 16:55:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-8783?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16548076#comment-16548076

Pavel Kovalenko commented on IGNITE-8783:
-----------------------------------------

[~avinogradov] Ok, now it makes sense. Btw, I propose to add explicit test with the hanging
scenario to make sure that after some future changes everything will work well. 18% of flaky
in suites not related directly to this functionality is not good point to demonstrate the
fix of the problem. So, after adding test, I think PR will be ready to merge.
We can make call on Friday when I return from vacation completely :)
