    Hi @shghatge ,
    This PR looks very nice; I added some minor inline comments to make it look even nicer
    One "major" problem: you have an example and a test for it; however, you don't have tests
for the GSAConfiguration itself; check https://github.com/apache/flink/blob/master/flink-staging/flink-gelly/src/test/java/org/apache/flink/graph/test/VertexCentricConfigurationITCase.java
    You need to make sure that given no direction; the iteration works as before and if you
give it direction IN or ALL, it behaves as it is supposed to. 
    Apart from that, this looks almost spotless.
    One other minor thing; when you make the PR, in order to have it uber - clean you should
squash your commits. In this case, you have 3 commits, so:
    git rebase -i HEAD~3 should do the trick
    Then leave pick for the first commit; squash for the others and let the instructions guide
you (Ctrl-x; Y, etc...). Then force push. 
    The common practice afterwards (i.e. after you address my comments here) is to leave it
as a new commit (don't squash!). So, first squash these 3, then fix the minor issues and commit
    Awesome work!

> For the time being, a vertex only gathers information from its in-edges.
> Similarly to the vertex-centric approach, we would like to allow users to gather data
from out and all edges as well. 
> This property should be set using a setDirection() method.
