Subject [jira] [Created] (IGNITE-5238) Ignite Spark can't be used with Ignite REST
Date Tue, 16 May 2017 18:48:04 GMT
Denis Magda created IGNITE-5238:
-----------------------------------

             Summary: Ignite Spark can't be used with Ignite REST
                 Key: IGNITE-5238
                 URL: https://issues.apache.org/jira/browse/IGNITE-5238
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Denis Magda
            Priority: Blocker
             Fix For: 2.1


{{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:

{code}

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.
