JongYoon Lim commented on HAMA-983:

Hi, it takes some time to understand Beam API, spark and flink runner for Beam. 
And it seems that Beam's transforms can be translated to Hama's API as follow. 
And BSP for dataflow could be similar to SuperstepBSP. (if I have 
misunderstandings, please correct me)  
ParDo -> Superstep
Read.Bound -> RecordReader
Writt.Bound -> RecordWriter
Combine -> Combiner
GroupByKey -> ? 

I'm about to start from batch mode first until Hama's streaming is ready. And 
I'll add sub-tasks for this soon.

> As you already know, Apache Beam provides unified programming model for both 
> batch and streaming inputs.
> The APIs are generally associated with data filtering and transforming. So 
> we'll need to implement some data processing runner like 
> https://github.com/dapurv5/MapReduce-BSP-Adapter/blob/master/src/main/java/org/apache/hama/mapreduce/examples/WordCount.java
> Also, implementing similarity join can be funny. According to 
> http://www.ruizhang.info/publications/TPDS2015-Heads_Join.pdf, Apache Hama is 
> clearly winner among Apache Hadoop and Apache Spark.
> Since it consists of transformation, aggregation, and partition computations, 
> I think it's possible to implement using Apache Beam APIs.
