syhily opened a new pull request, #20567:
URL: https://github.com/apache/flink/pull/20567
## What is the purpose of the change
Pulsar's client provides a `Consumer.seek()` method for setting the start
position. This method would cause the race condition sometimes, which may lead
to duplicated messages in consuming results. This is unacceptable and we have
to use Pulsar admin API instead.
## Brief change log
* Drop `Consumer.seek()` in `PulsarPartitionSplitReaderTestBase`
