> Flaky tablet_history_gc-itest due to interleaving of concurrent client flushes
> ------------------------------------------------------------------------------
>
> Key: KUDU-1761
> URL: https://issues.apache.org/jira/browse/KUDU-1761
> Project: Kudu
> Issue Type: Bug
> Components: client, test
> Affects Versions: 1.1.0
> Reporter: Mike Percy
> Assignee: David Alves
> Fix For: 1.2.0
>
>
> It appears that tablet_history_gc-itest is flaky due to interleaving of
> client operations when automatic flush is enabled. The test is particularly
> susceptible if an async flush is triggered after each operation.
> The issue becomes more apparent when there are two updates to the same row in
> quick succession, and an async flush is triggered after each one. Sometimes
> the 2nd update is applied first on the server, then overwritten by the 1st
> update, even though it was applied first to the client session. This
> concurrency race may manifest randomly in response to thread and network
> timing latencies.
