jihoonson opened a new pull request #7339: Fix exclusive start partitions for sequenceMetadata
URL: https://github.com/apache/incubator-druid/pull/7339
 
 
   The Kafka/Kinesis task generates `sequenceMetadata`s from the task context when it is started and `restoreSequences` returns false. Currently, the first sequence always has inclusive start partitions and subsequent sequences always have exclusive start partitions. This is not true both in Kinesis and Kafka indexing service. In Kafka indexing service, the start partitions are always inclusive. In Kinesis indexing service, only the very first sequence which is created when the supervisor is started has inclusive start partitions. Others should have exclusive start partitions.
   
   I also fixed [this line](https://github.com/apache/incubator-druid/blob/master/indexing-service/src/main/java/org/apache/druid/indexing/seekablestream/SeekableStreamIndexTaskRunner.java#L652).
