== Pros and Cons of Spark == The main advantages of Spark on Hyak: # Work with "big data" without ever running out of memory. # You get very good parallelism for free. # Distribute computational work across many hyak nodes so your programs run faster. # Common database operations (select, join, groupby, filter) are pretty easy. # Spark supports common statistical and analytical tasks (stratified sampling, summary and pairwise statistics, common and simple models). # Spark is a trendy technology that lots of people know or want to learn. The main disadvantages of Spark are # It takes several steps to get the cluster up and running. # The programming paradigm is not super intuitive, especially if you are not familiar with SQL databases or lazy evaluation. # Doing more advanced things requires programming in Scala.
