July 2nd to 6th, from 15:00 to 18:00h



We are going to explain how Data Scientist trained to work with R can work with Hadoop without need to learn Scala. We will discuss two possible workflows.

  • First approach is using SQL on Hive or Impala. This implies that the most important part of analysis has to be done locally.
  • Second method is to try to do some part of analysis on clusters using sparkR/sparklyR.

Both methods have their advantages and limitations. We are going to discover them by working on a project that involves creating predictive model.


Lecture plan

  • Data Scientist vs. Big Data: DS workflow.
  • Big Data Storage. 
  • Hive/Impala/Spark: adding SQL to R.
  • Analytics and Machine Learning on clusters with sparkR: opportunities and limitations. Comparing R/Python/Scala.



Project that involves train and test predictive model.
