[VOTE] 0.10.2.0 RC0
Hello Kafka users, developers and client-developers,
This is the first candidate for release of Apache Kafka 0.10.2.0.
This is a minor version release of Apache Kafka. It includes 19 new KIPs.
See the release notes and release plan (
https://cwiki.apache.org/confluence/display/KAFKA/Release+Plan+0.10.2.0)
for more details. A few feature highlights: SASL-SCRAM support, improved
client compatibility to allow use of clients newer than the broker, session
windows and global tables in the Kafka Streams API, single message
transforms in the Kafka Connect framework.
Release notes for the 0.10.2.0 release:
http://home.apache.org/~ewencp/kafka-0.10.2.0-rc0/RELEASE_NOTES.html
*** Please download, test and vote by Monday February 6th 5pm PST ***
(Note the longer window to vote to account for the normal 7 days ending in
the middle of the weekend.)

Unfortunately we had a regression in streams and KAFKA-4716 is now deemed a Blocker. https://issues.apache.org/jira/browse/KAFKA-4716 <https://issues.apache.org/jira/browse/KAFKA-4716>

All,
It sounds like https://issues.apache.org/jira/browse/KAFKA-4725 is a
regression in an earlier release and worth fixing. I've marked it blocker
for 0.10.2.0. I'll plan to roll a new RC once it is committed (some stress
testing of the one-line patch is currently ongoing).

Hi Ewen,
I tested the quickstart with this release candidate on Ubuntu, Windows (32
and 64 bit) and Mac.
Everything looks good, except for one issue on Windows 7 32 bit when
running the WordCount demo application from the Kafka Streams step.
Running that command gave me this error, and as a result, no data was
written to the output topic:

Huh, that's surprising to me given that site-docs are part of the artifacts
voted on. Having a way to update docs between releases is actually
different from considering a known docs bug an issue w/ the release if
someone cares about the site-docs artifacts being correct. But the
site-docs seem somewhat pointless anyway. As a standalone package they
don't work properly because they import files that only exist in the
kafka-site repo...
I've tracked down all but one of the issues w/ docs. One was a bad rule in
the .htaccess file which I've fixed (and that isn't in the release
artifacts). A few others are changes that got made to kafka-site but
weren't properly ported back to the docs/ directory in the main repo. As
soon as I sort out the last problem (the double menu issue) I will submit a
PR to get us back in sync w/ kafka-site.

Note that doc fixes do not require new RC (we fix docs between
releases). So unless bugs are found, you won't need to do another.

Thanks for testing Vahid. Let me check in with Derrick, who made some
adjustments to our handling of docs and other versions. I'm wondering if
this could only affecting this page due to changes that were made in
kafka-site and not included in the main Kafka repo. I found some other
changes where they differed when doing some other docs updates.
I'm seeing now that the protocol link doesn't seem to work on the previous
release either. We'll have to figure out when that change to a fragment
happened.
I figured we'd end up w/ more RCs. Please still test the other artifacts
since a docs change like this will be a trivial next RC.

Ewen,
Thanks a lot for running the release. I checked some of the links in the
email and noticed a couple of issues:
When I go to the documentation link (
http://kafka.apache.org/0102/documentation.html) and scroll down I get a
second left-nav when I reach the end of list of content (try this link:
http://kafka.apache.org/0102/documentation.html#gettingStarted). I see
this on both Safari and Firefox.
The link for protocol (http://kafka.apache.org/0102/protocol.html)
redirects me to (http://kafka.apache.org/0102/documentation#protocol)
which doesn't seem to be valid.

Re: [VOTE] 0.10.2.0 RC0
Posted by Tom Crayford <tc...@heroku.com>.
-1 (non-binding). Whilst testing 0.10.1.1, we found that there's a bug with
quotas that means clients can cause broker OOMs very easily. If a producer
has exceeded the produce quota, the produce request memory is retained
inside the delay queue. (https://issues.apache.org/jira/browse/KAFKA-4725).
Seeing as this bug critically impacts broker stability in the face of quota
enforcement, I'd like to see a fix landed (we're working on a patch
already, see
https://github.com/apache/kafka/compare/0.10.1.1...heroku:fix-throttled-response-leak,
but it's not quite ready yet).
This bug is still present in 0.10.2.0 RC0
To quote KIP-13 on this matter:
> Note that in case of producers, we should be careful about retaining
references to large Message bodies because we could easily exhaust broker
memory if parking hundreds of requests.
