--------------------------------------
Assignee: Sergey Soldatov
> Don't keep failed requests in the RetryCache.
> ----------------------------------------------
>
> Key: RATIS-2385
> URL: https://issues.apache.org/jira/browse/RATIS-2385
> Project: Ratis
> Issue Type: Improvement
> Components: common
> Affects Versions: 3.2.1
> Reporter: Sergey Soldatov
> Assignee: Sergey Soldatov
> Priority: Major
>
> We are caching the requests in the RetryCache once we receive those. There is
> a chance that the request fails due to the leader change. In this case, the
> request would fail, and it would stay in the RetryCache with the failure. As
> a result, if the app is relying on the RetryCache, it might continuously fail
> the request during the retries. See HDDS-13621 as an example.
> The solution should be straightforward. If we fail the request after we've
> started processing it but before we put it to the log file, we should remove
> it from the RetryCache.
