Scala 2.10 support

[vveider]

Hi, Igniters!


While working on Java 9 support adaptation, came to a problem with scala
2.10 and corresponding modules (scala-2.10, spark-2.10 and
visor-console-2.10) which will not compile under Java 9. As I see here [1]
scala 2.10 is already deprecated in spark 2.1.0 (and lately spark version
updated to 2.2.0 in master).

So, I'd like to propose scala-2.10, spark-2.10 and visor-console-2.10
modules for deletion in 2.4 release.

Support for scala 2.11.x (which also will not compile under Java 9) will be
maintained by maven profiles.

How much of an effort will be to support scala and spark 2.10?

As much as I see, scala-2.10, spark-2.10 and visor-console-2.10 modules require scala 2.10 by dependency, which is not going to work any way (or at least without some hacky hack) with Java 9.
Considering Java 9 to be strictly 2.4+ functionality — I guess it is more or less solid approach in dropping support of deprecated (for some decent time) technologies in next releases in favour of the newest ones where there is no other proper way of utilising them both.

I agree that we should drop it, I just want to understand how difficult it
is. What is the amount of effort associated with this change?

From the point of build configuration — it is required to delete modules/{scalar-2.10,spark-2.10,visor-console-2.10} directories and corresponding modules from pom.xml (they are currently disabled in ignite-6730).
From the point of project operability and consistency — I’ve started this discussion just to hear opinions on subject from Ignite experts will there be any pitfalls in simple modules removal from project.
