> Key: FLINK-27399
> URL: https://issues.apache.org/jira/browse/FLINK-27399
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Pulsar
> Affects Versions: 1.14.4, 1.15.0, 1.16.0
> Reporter: Yufan Sheng
> Assignee: Yufan Sheng
> Priority: Blocker
> Labels: pull-request-available
> Fix For: 1.16.0, 1.15.2, 1.14.6
>
>
> The Pulsar connector didn't use the consuming position from the checkpoint.
> They just commit the position to Pulsar after the checkpoint is complete. And
> the connector starts to consume messages from Pulsar directly by the offset
> stored on the Pulsar subscription.
> This causes the test could be failed in some situations. The start cursor
> (position on Pulsar) would be reset to the wrong position, which caused the
> results didn't match the desired records.
> h2. How to fix this issue
> Change the start position seeking mechanism from Pulsar consumer API to
> Pulsar admin API. Don't reset the start position when the topic has a
> subscription.
