Description
Ignite Hadoop Accelerator Distribution contains only ignite-spark of version 2.11 which makes impossible to downgrade to ignite of version 2.10 if it's needed.
Let's include both libraries (ignite-spark 2.10 and 2.11) in Ignite Hadoop Accelerator Distribution under the libraries 'optional' folder.
Refer to the discussion on the dev list:
