> 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
> Priority: Critical
> 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.
