Hi! I've stumbled upon this: https://issues.apache.org/jira/browse/HAMA-983 and it got me thinking that perhaps we can also do something similar for Giraph.
Am I missing something here or could be it pretty powerful way to expose Giraph to even more users? Thanks, Roman. P.S. Also this: http://www.ruizhang.info/publications/TPDS2015-Heads_Join.pdf gives an interesting perspective on BSP vs. MR vs. Spark.
