---------------------------------------

             Summary: NPE when trying to submit Hadoop job to a node where Hadoop module is not loaded.
                 Key: IGNITE-2101
                 URL: https://issues.apache.org/jira/browse/IGNITE-2101
             Project: Ignite
          Issue Type: Bug
          Components: hadoop
    Affects Versions: ignite-1.4
            Reporter: Vladimir Ozerov
             Fix For: 1.6


See http://apache-ignite-users.70518.x6.nabble.com/NPE-issue-with-trying-to-submit-Hadoop-MapReduce-td2146.html

When Hadoop module is not loaded, HadoopNoopProcessor is started on the node. And it's method nextJobId() returns null. This null is then propagated to the client and NPE is raised. There is no way for users to underastand what is wrong.

Solution should be fairly simple: just throw an exception with sensible message from HadoopNoopProcessor.nextJobId() method. It should be propagated smoothly to the client.
Also we need to add tests for this scenario.
