> Kylin5 encounters metadata anomalies when concurrently submitting
> build/refresh tasks
> -------------------------------------------------------------------------------------

> Key: KYLIN-6028
> URL: https://issues.apache.org/jira/browse/KYLIN-6028
> Project: Kylin
> Issue Type: Bug
> Affects Versions: 5.0.0
> Reporter: Guoliang Sun
> Priority: Major
>
> In Kylin5, when two incremental build tasks with the same time range for the
> same model are submitted concurrently, both requests succeed. However, only
> one segment is created for the model, while two build tasks are created,
> which is inconsistent with expectations.
> Further verification shows that the same issue occurs when concurrently
> refreshing the same segment.
> Additional testing reveals that submitting build/refresh tasks concurrently
> for a model may result in issues, regardless of whether these tasks conflict
> or not.
