Thanks Ismael for the tip.
I missed it in the Readme page (

If you don't use the default Scala version, you have to set the
SCALA_VERSION environment variable for the bin scripts to work.

Hello Kafka users, developers and client-developers,

This is the second candidate for release of Apache Kafka 1.0.0.

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.
See the release notes and release plan

for more details. A few feature highlights:

* Java 9 support with significantly faster TLS and CRC32C implementations
(KIP)
* JBOD improvements: disk failure only disables failed disk but not the
broker (KIP-112/KIP-113)
* Newly added metrics across all the modules (KIP-164, KIP-168, KIP-187,
KIP-188, KIP-196)
* Kafka Streams API improvements (KIP-120 / 130 / 138 / 150 / 160 / 161),
and drop compatibility "Evolving" annotations

Hi Ghouzang,

We have indeed started our performance testing at Heroku for RC1. However,
we are more than happy to retest once RC2 is available, especially given
larger amounts of time to do so.

Thanks

After specifying the location of zookeeper jar:

export CLASSPATH=

The command can be executed successfully:

bin/zookeeper-server-start.sh config/zookeeper.properties

This doesn't seem to be Java 9 specific issue.

Re: [VOTE] 1.0.0 RC1

[Vahid S Hashemian]

Hi Guozhang,

I'm not sure if this should be covered by "Java 9 support" in the RC note, 
but when I try to build jars from source using Java 9 (./gradlew 
-PscalaVersion=2.12 jar) even though the build reports as succeeded, it 
doesn't seem to have been successful:

$ bin/zookeeper-server-start.sh config/zookeeper.properties
Error: Could not find or load main class 
org.apache.zookeeper.server.quorum.QuorumPeerMain
Caused by: java.lang.ClassNotFoundException: 
org.apache.zookeeper.server.quorum.QuorumPeerMain

Please advise if I'm missing something.

Thanks.

Hello Kafka users, developers and client-developers,

This is the second candidate for release of Apache Kafka 1.0.0.

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.
See the release notes and release plan
(*https://urldefense.proofpoint.com/v2/url?u=https-3A__cwiki.apache.org_confluence_pages_viewpage.action-3FpageId-3D71764913=DwIBaQ=jf_iaSHvJObTbx-siA1ZOg=Q_itwloTQj3_xUKl7Nzswo6KE4Nj-kjJc7uSVcviKUc=VyLkHrCpgoKOD8nDthZgGw_OWk2y2QfKYsXitTyAHHM=tT9k0x5RvXtHEtLzp03BA1Y8DAgHzgCXD7UjqP7oiKE=

>*)
for more details. A few feature highlights:

* Java 9 support with significantly faster TLS and CRC32C implementations
(KIP)
* JBOD improvements: disk failure only disables failed disk but not the
broker (KIP-112/KIP-113)
* Newly added metrics across all the modules (KIP-164, KIP-168, KIP-187,
KIP-188, KIP-196)
* Kafka Streams API improvements (KIP-120 / 130 / 138 / 150 / 160 / 161),
and drop compatibility "Evolving" annotations

Re: [kafka-clients] Re: [VOTE] 1.0.0 RC1

[Jun Rao]

Hi, Guozhang,

Onur found an existing performance bug in the controller when there are
lots of partitions. The fix is simple (
https://github.com/apache/kafka/pull/4075) and reduces the controlled
shutdown time from 6.5 mins to 30 secs, with
25K partitions, RF=2 and 5 brokers.

It would be useful to include this fix in 1.0.0.

Thanks,

Jun

Re: [VOTE] 1.0.0 RC1

[Guozhang Wang]

Hi Tom,

Thanks for pointing it out. I meant to say Oct. 17th, Tuesday, for a 72
hours period.

That being said, we need to have a lazy majority to accept a release RC
according to our bylaws (
https://cwiki.apache.org/confluence/display/KAFKA/Bylaws). And if we cannot
achieve that via thorough testing within the period we will automatically
extend the voting process.

Re: [VOTE] 1.0.0 RC1

[Thomas Crayford]

Hi Guozhang,

This says the due date on the testing is October 13th, which was the day
this email was sent. Is that accurate, or is it meant to read October 17th,
which is next Tuesday?

I feel like this short a testing window for a 1.0 RC is a little low, as
1.0 is clearly a big announcement of stability, and folk should be given
enough time to do thorough testing.

Thanks

Tom

[VOTE] 1.0.0 RC1

[Guozhang Wang]

Hello Kafka users, developers and client-developers,

This is the second candidate for release of Apache Kafka 1.0.0.

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.
See the release notes and release plan
(*https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=71764913
*)
for more details. A few feature highlights:

* Java 9 support with significantly faster TLS and CRC32C implementations
(KIP)
* JBOD improvements: disk failure only disables failed disk but not the
broker (KIP-112/KIP-113)
* Newly added metrics across all the modules (KIP-164, KIP-168, KIP-187,
KIP-188, KIP-196)
* Kafka Streams API improvements (KIP-120 / 130 / 138 / 150 / 160 / 161),
and drop compatibility "Evolving" annotations
