Hi Guozhang, I was able to successfully build the jars on Ubuntu (Java 8 and 9) and Mac (Java 8) and run the quickstart (incl. streams quickstart).
On Windows 10, build worked fine with both Java 8 and 9. Quickstarts worked well too, except for streams quickstart, where the following command bin\windows\kafka-run-class.bat org.apache.kafka.streams.examples.wordcount.WordCountDemo constantly crashed Java for me, with the error: "An unhandled win32 exception occurred in java.exe". This is what shows up in the broker log before the crash: [2017-10-17 15:09:13,948] INFO [GroupCoordinator 0]: Preparing to rebalance group streams-wordcount with old generation 0 (__consumer_offsets-35) (kafka.coordinator.group.GroupCoordinator) [2017-10-17 15:09:13,964] INFO [GroupCoordinator 0]: Stabilized group streams-wordcount generation 1 (__consumer_offsets-35) (kafka.coordinator.group.GroupCoordinator) [2017-10-17 15:09:14,214] INFO [GroupCoordinator 0]: Assignment received from leader for group streams-wordcount for generation 1 (kafka.coordinator.group.GroupCoordinator) And this shortly after: [2017-10-17 15:09:24,230] INFO [GroupCoordinator 0]: Member streams-wordcount-5fd1c2b1-f050-45a3-a331-66832cf34f83-StreamThread-1-consumer-71a4d57c-9f40-4340-8f71-5549187331d3 in group streams-wordcount has failed, removing it from the group (kafka.coordinator.group.GroupCoordinator) [2017-10-17 15:09:24,230] INFO [GroupCoordinator 0]: Preparing to rebalance group streams-wordcount with old generation 1 (__consumer_offsets-35) (kafka.coordinator.group.GroupCoordinator) [2017-10-17 15:09:24,230] INFO [GroupCoordinator 0]: Group streams-wordcount with generation 2 is now empty (__consumer_offsets-35) (kafka.coordinator.group.GroupCoordinator) I also noticed another issue on Windows that I reported in KAFKA-6075. That issue is not specific to the release candidate though.

The main PRs that gets merged in after RC1 are the following: https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_apache_kafka_commit_dc6bfa553e73ffccd1e604963e076c78d8ddcd69&d=DwIBaQ&c=jf_iaSHvJObTbx-siA1ZOg&r=Q_itwloTQj3_xUKl7Nzswo6KE4Nj-kjJc7uSVcviKUc&m=Y-4kiSVRo1wsHsySpb2cQHh-ex6Y29UAzo2cqTjH170&s=x_8A9EHvjlL9exX6PRNWYQLinf7VaKbx8Rwmn_IoK98&e= It's worth noting that starting in this version we are using a different version protocol with three digits: *major.minor.bug-fix* Any and all testing is welcome, but the following areas are worth highlighting: 1. Client developers should verify that their clients can produce/consume to/from 1.0.0 brokers (ideally with compressed and uncompressed data). 2. Performance and stress testing. Heroku and LinkedIn have helped with this in the past (and issues have been found and fixed). 3. End users can verify that their apps work correctly with the new release. This is a major version release of Apache Kafka. It includes 29 new KIPs.
