Hey Harsha, I noticed that you proposed that Storm should drop support for Java 7 in master: http://markmail.org/message/25do6wd3a6g7cwpe It's useful to know what other Apache projects are doing in this regard, so I'm interested in the timeline being proposed for Storm's transition. I could not

Hi Ismael, thanks for the pointer to the latest WebSphere documentation - I wasn’t aware of that release. We currently have customers that run our software frontend on an older WebSphere version that runs on Java 7 and push data to kafka brokers in the backend. Replacing Kafka brokers wouldn’t

Hi Ismael, Agree on timing is more important. If we give enough heads up to the users who are on Java 7 thats great but still shipping this in 0.10.x line is won't be good as it still perceived as maint release even the release might contain

+1 We can't promise security features whilst using a deprecated version of the JDK and relying on it for underlying security functionality (e.g. SSL). This impacts both clients and brokers. Java 7 has been deprecated for over a year, and software that isn't up to date with that is at fault with re

Re: [DISCUSS] Java 8 as a minimum requirement

I also think that Kafka should drop java 7 and scala 2.10 already. However, I expect Kafka (or any other project) to do it in two steps: 1. announce NOW that both of them are deprecated in the 0.10 series and will be dropped in the next major release. 2. drop them a the next major release. (ideall

Re: [DISCUSS] Java 8 as a minimum requirement

Scala 2.12 requires JDK 8 to take advantage of JVM technology. Forcing migration to JDK 8 explains to some extent the non rush to release 2.12.

I totally agree with Marcus. No issue in upgrading the broker's code to 8. For the client, there can be lots of users which are required to stay 7 because of dependencies. So, stay with 7 at least for the client. And... if you break compatibility to 7 please do that in a major release. *Valeri

I agree with Harsha and Marcus. Many of the kafka users are still on java 7 and some of them definitely upgrade to newer versions. We may need to support for a while. We can remove the support from next major version onwards. Thanks, Manikumar On Fri, Jun 17, 2016 at 2:04 PM, Marcus Gründler wr

Hi Harsha, Are you saying that you are aware of many Kafka users still using Java 7 who would be ready to upgrade to the next Kafka feature release (whatever that version number is) before they can upgrade to Java 8? The 0.10.1 versus 0.11.0.0 is something that can be discussed separately as no d

Hi Ismael, Unfortunately Java 8 doesn't play nice with FreeBSD. We have seen a lot of JVM crashes running our 0.9 brokers on Java 8... Java 7 on the other hand is totally stable. Until these issues have been addressed, this would cause some serious issues for us. Regards Jan

I definitely think its time, but I am not sure if 0.10.1.0 is the release version to drop support in. Would it make sense to drop Java 1.7 and Scala 2.10 support in Kafka 0.11 to maintain upgrade compatibility throughout the 0.10.x series? As a side note, I personally like the pattern of always s
