Hi, Igniters I've started the work on the Spark 2.4 support We started the discussion here, in https://issues.apache.org/jira/browse/IGNITE-12054
The Spark internals were totally refactored between 2.3 and 2.4 versions, main changes touches - External catalog and listeners refactoring - Changes of HAVING operator semantic support - Push-down NULL filters generation in JOIN plans - minor changes in Plan Generation that should be adopted in our integration module I propose the initial solution here via creation of new module spark-2.4 here https://issues.apache.org/jira/browse/IGNITE-12247 and addition of new profile spark-2.4 (to avoid possible clashes with another spark versions) Also I've transformed ticket to an Umbrella ticket and created a few tickets for muted tests (around 7 from 211 tests are muted now) Please, if somebody interested in it, make an initial review of modular ignite structure and changes (without deep diving into Spark code). And yes, the proposed code is a copy-paste of spark-ignite module with a few fixes
