             Summary: Ensure that Hadoop client is still operational after failed map-reduce
jobs.
                 Key: IGNITE-2354
                 URL: https://issues.apache.org/jira/browse/IGNITE-2354
             Project: Ignite
          Issue Type: Bug
          Components: hadoop
    Affects Versions: ignite-1.4
            Reporter: Vladimir Ozerov
            Assignee: Ivan Veselovsky
            Priority: Critical
             Fix For: 1.6


We need to ensure that MR failures on the server doesn't block further job submissions. 

First of all we should cover such situations with tests.
1) Test exceptions on all job stages (setup, map, reduce, combine, cleanup)
2) Test several exception types: 
- Exceptions expected from Hadoop interface
- Exceptions unexpected form Hadoop interface
- Errors.
