Subject Re: Scala 2.10 support
Date Wed, 10 Jan 2018 19:36:11 GMT
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.
