-------------------------------------
[~roman_s], once you get positive results from TC please assign the ticket to
me. I'll check the changes against the example used at conferences.

> {{ignite-rest-http}} can't be used together with {{ignite-spark}} because the
> former imports some legacy version of Jackson library and the following
> exception is thrown from an IDEA in attempt to use Ignite+Spark application:

> To reproduce:
> - Download this project and open in IntellijIdea:
> https://github.com/dmagda/IgniteSparkIoT
> - Go to pom.xml and uncomment {{ignite-rest-http}} module. It has to be
> imported.
> - Start a cluster node with IgniteNodeStartup
> - Start SparkStreamerStartup and you will get the error above.
> Looks like the Ignite REST module has to be upgraded to the recent Jackson
> version.
