--------------------------------------

             Summary: Create new API for Process dependency graph DAG which captures process
connected via feeds
                 Key: FALCON-256
                 URL: https://issues.apache.org/jira/browse/FALCON-256
             Project: Falcon
          Issue Type: Improvement
            Reporter: Shaik Idris Ali


Currently Falcon has dependency APIs which lists the entity dependencies.
i.e. A dependency of a process lists all the input and output feeds and corresponding clusters.

With the new process DAG API, it should generate .DOT file which can be easily converted to
visual graph.

All the processes are linked by the configured feeds.
EX: If process A generates feeds 1,2 and feed 1 is consumed by process B and 2 by process
C respectively, then the .DOT file should generate adjacency matrix.
Graph start{
A -> B
A -> C
..
..
B->D
D->E
}

Unless we build dashboard this API will be handy for users.
