[DISCUSS] Drop Scala 2.11
Hi Everyone,
Think of this as a pre-flip, but what does everyone think about dropping
Scala 2.11 support from Flink.
The last patch release was in 2017 and in that time the scala community has
released 2.13 and is working towards a 3.0 release. Apache Kafka and Spark
have both dropped 2.11 support in recent versions. In fact, Flink's
universal Kafka connector is stuck on 2.4 because that is the last version
with scala 2.11 support.
What are people's thoughts on dropping Scala 2.11? How many are still using
it in production?

Re: [DISCUSS] Drop Scala 2.11
Posted by Theo Diefenthal <th...@scoop-software.de>.
We use a Cloudera 6.3 cluster in prod. I'd guess that it's still widely used in prod as those cloudera upgrades for major versions are planned long time ahead and take a significant amount of resources in big data lakes.
On that 6.3. cluster, if I open spark-shell, I still see scala 2.11 in use:
> Using Scala version 2.11.12 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_181)
Just to don't mess with any dependencies and as we have both, Flink and Spark jobs, we declare all dependencies with scala_2.11. But we never actually tried what happens if we would change that. We just seek maximum compatibility while at the same time, maintain and upgrade Flink ourselves to keep up with the development pace of the fast community and being able to use the latest major version quickly.
So my suggestion: As long as it isn't much pain, I'd like to keep the scala 2.11 support for a while. (or even better for me as a Java, but never scala developer: Drop it completely :) ) Speaking for my project: I think our ops team plans to upgrade to Cloudera 7 somewhere around Q2 2021, so personally I'm fine with dropping it then.
Best regards
Theo

Yes, we would absolutely migrate statefun. StateFun can be compiled with Scala 2.12 today, I'm not sure why it's not cross released.

@mathieu Its on the roadmap but it's non-trivial and I'm not aware of anyone actively working on it.

That makes sense.
We are using 2.12 for our production
Also, for flink scala 2.12 support, it is in fact limited to scala 2.12.7.
It is binary incompatible with version 2.12 above (
[ https://issues.apache.org/jira/browse/FLINK-12461 | https://issues.apache.org/jira/browse/FLINK-12461 ] )
That would be great to at least move to a more recent 2.12 version, and
ideally to 2.13.
Is there any scala support plan available?

Glad to see someone in community would like to drive this effort.
If scala 2.13 can do whatever scala 2.11 can do in flink (such as support
scala-shell, scala lambda udf and etc), then I would be 100% support of
dropping scala 2.11.

Re: [DISCUSS] Drop Scala 2.11
Posted by Aljoscha Krettek <al...@apache.org>.
There is some new enthusiasm for bringing Scala 2.13 support to Flink:
https://issues.apache.org/jira/browse/FLINK-13414.
One of the assumed prerequisites for this is dropping support for Scala
2.11 because it will be too hard (impossible) to try and support three
Scala versions at the same time.
What do you all think now that some time has passed?
I would still be in favour of dropping Scala 2.11 but I can see Theo's
point of people being tied to distro releases. On the other hand, Scala
2.11 is quite old now and some projects (such as Kafka) don't release
newer versions with Scala 2.11 support.
Best,
Aljoscha

I would hope we can make scala shell with scala 2.12 before dropping 2.11,
many users are still using scala shell to try out new features of flink,
especially for new users.

Are we then also dropping the scala-shell, since it still doesn't work

Big +1 to drop Scala 2.11
This would mean that we can finally use Java 8 language features that
are integrated with Scala.

Re: [DISCUSS] Drop Scala 2.11
Posted by Theo Diefenthal <th...@scoop-software.de>.
We use a Cloudera 6.3 cluster in prod. I'd guess that it's still widely used in prod as those cloudera upgrades for major versions are planned long time ahead and take a significant amount of resources in big data lakes.
On that 6.3. cluster, if I open spark-shell, I still see scala 2.11 in use:
> Using Scala version 2.11.12 (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0_181)
Just to don't mess with any dependencies and as we have both, Flink and Spark jobs, we declare all dependencies with scala_2.11. But we never actually tried what happens if we would change that. We just seek maximum compatibility while at the same time, maintain and upgrade Flink ourselves to keep up with the development pace of the fast community and being able to use the latest major version quickly.
So my suggestion: As long as it isn't much pain, I'd like to keep the scala 2.11 support for a while. (or even better for me as a Java, but never scala developer: Drop it completely :) ) Speaking for my project: I think our ops team plans to upgrade to Cloudera 7 somewhere around Q2 2021, so personally I'm fine with dropping it then.
Best regards
Theo

That makes sense.
We are using 2.12 for our production
Also, for flink scala 2.12 support, it is in fact limited to scala 2.12.7.
It is binary incompatible with version 2.12 above (
[ https://issues.apache.org/jira/browse/FLINK-12461 | https://issues.apache.org/jira/browse/FLINK-12461 ] )
That would be great to at least move to a more recent 2.12 version, and
ideally to 2.13.
Is there any scala support plan available?

Re: [DISCUSS] Drop Scala 2.11

Yes! I would be in favour of this since it's blocking us from upgrading
certain dependencies.
I would also be in favour of dropping Scala completely but that's a
different story.

Re: [DISCUSS] Drop Scala 2.11

I'd be fine with dropping Scala 2.11. Stateful Functions currently requires
2.11, though, so that would have to be addressed as well.
I'm using 2.11 in a production project now but only because of the Stateful
Functions dependency. If I could use a newer Scala version that would be
fine/preferred.
