[jira] [Commented] (IGNITE-7324) AssertionError Entry cannot become
obsolete when DHT local candidate is added in deadlock detection suite
[ https://issues.apache.org/jira/browse/IGNITE-7324?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16429706#comment-16429706 ]

-------------------------------------------
[~agoncharuk]
The issue often causes TC run failures for new tests added in IGNITE-6827 which I'm currently working on.
If you don't mind I'll take it.

> It looks like the lock future has acquired one lock and was waiting for another lock. When the future timed-out, the previous lock was already removed, but the next lock was successfully acquired, which led to the assertion above.
> My suggestion would be to give up in the mapping code if the future has timed out or if we got entry removed exception
