> Currently there are multiple join implementations in Malhar. 
> One is an inner join implementation based on managed state, and another is a merge operator
based on the windowed operator and uses spillable data structures.
> This JIRA is to remove the inner join implementation from malhar - org/apache/apex/malhar/lib/join/
> The merge operator also needs to be simplified - perhaps by providing a wrapper around
it which can be used without requiring any knowledge of windowing concepts. This will be a
separate JIRA.
