> Distributed cache files cannot be accessed when working in Iterative contexts. While
constructing the context in {{AbstractIterativePactTask}}, the distributed entries are not
passed on to runtime context.
> My commit will add this and also unify the distributed cache system to work everywhere,
including in the Collection Environment.
