Subject Re: Spark examples on TC

Nikolay,

Thanks for the details. How about enforcing JDK 8 for the Spark integration
in general and run its tests on the VM only? We'll do this until Spark
community fully support JDK 11+.

As for Spark 2.4.0 module [1], how about releasing Ignite 2.7.7 with Spark
related changes only? As long as Ignite modularization is a long process,
we can follow your advice and create two more modules ignite_spark_24 and
ignite_spark_25 . Plus Alexey is working on extra Spark improvements.
