Grant Henke updated KUDU-1779:
------------------------------
Target Version/s: (was: 1.8.0)
> Consensus "stuck" with all transaction trackers are at limit
> ------------------------------------------------------------
>
> Key: KUDU-1779
> URL: https://issues.apache.org/jira/browse/KUDU-1779
> Project: Kudu
> Issue Type: Bug
> Components: consensus
> Affects Versions: 1.1.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Critical
> Labels: stability
>
> In a stress cluster, I saw one tablet get "stuck" in the following state:
> - the transaction_tracker on all three replicas is "full" (no more can be
> submitted)
> - leader elections proceed just fine, but no leader is able to advance the
> commit index
> The issue seems to be that a replica will respond with 'CANNOT_PREPARE' when
> its transaction tracker is full. The leader then ignores this response, and
> doesn't advance the majority-replicated watermark. The transaction tracker
> stays full forever because the in-flight transactions can't get committed.
> Notes to follow.
