>             Project: Ignite
>          Issue Type: Task
>          Components: hadoop
>    Affects Versions: ignite-1.4
>            Reporter: Vladimir Ozerov
>            Assignee: Vladimir Ozerov
>            Priority: Critical
>
> Several major problems with internal job execution were revealed:
> 1) Native code cannot run normally.
> 2) Excessive permgen allocations
> 3) We must use some dirty hacks to prevent classloader leaks (see mocked classes in HadoopClassLoader).
> External execution must help us with it. 
> The problem is that it never worked properly. We must restore it and then test very thoroughly.
