[Beowulf] Clustering vs Hadoop/spark

Hi Ben,

Readded the list

I think where im confused is that to me doesn’t that what Hadoop/Spark does distributes the data for computation then aggregates it back into a single data set?

Correct me if I am wrong here. 

Also another thing I cant seem to understand is how for big data analytics a java based platfrom manages to get some great performance to crunch large data sets.

can you distribute any application without programming against a framework?

We distribute a lot of data parallel tasks with the source code unchanged via SLURM.
