I am planning to take CCA-175 end of March this year, I wanted to know if Spark Streaming is part of the CCA-175 test or not? If it's not, then is it going to be included when I would be taking the exam?
Same about Spark SQL. Are there any plans to make it part of the test around this time?
The current set of skills tested for Spark include loading, filtering, sorting, aggregation, and joining. This is called out on the page http://www.cloudera.com/training/certification/cca-spark.html#skills Spark Streaming and Spark SQL are not currently mentioned.
In the future as new version of CDH come out, you can expect the list of required skills to change. Watch the website for announcements.
