Marco Lotz updated KAFKA-9527: ------------------------------ Description: When running the streams application reset tool with --by-duration or --to-datetime if any partitions for a given input topic are empty a NPE is thrown. I tested this with a topic with 3 partitions, I received a NPE until all 3 partitions had at least one message. The behavior was the same for both --to-datetime and --by-duration. Error below: Reset-offsets for input topics [sample-cdc-topic]Reset-offsets for input topics [sample-cdc-topic]Following input topics offsets will be reset to (for consumer group des-demo-stream)ERROR: java.lang.NullPointerExceptionjava.lang.NullPointerException at kafka.tools.StreamsResetter.resetToDatetime(StreamsResetter.java:496) at kafka.tools.StreamsResetter.maybeReset(StreamsResetter.java:426) at kafka.tools.StreamsResetter.maybeResetInputAndSeekToEndIntermediateTopicOffsets(StreamsResetter.java:374) at kafka.tools.StreamsResetter.run(StreamsResetter.java:164) at kafka.tools.StreamsResetter.run(StreamsResetter.java:131) at kafka.tools.StreamsResetter.main(StreamsResetter.java:678) was: When running the streams application reset tool with --by-duration or --to-timestamp if any partitions for a given input topic are empty a NPE is thrown.
