Hi Praveen, good to hear that your cluster is now up and running.
You can calculate the betweenness/centrality with ArangoDB but you have to make sure that the result set will fit in memory on 1 machine. Depending on your queries it might grow quite large. There are even better algorithms for betweenness/centrality but not implemented into ArangoDB yet. The Pregel algorithm takes another approach to handle distributed graphs. We are currently in the very beginning of looking into Pregel so we can´t say if or when Pregel will be implemented into ArangoDB In terms of Eigenvector I have to say that this is currently not possible with ArangoDB. I hope I could help a bit.
