---------------------------------------
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.
