Ask HN: Should I get Apache Spark certification?

Hello all, I am currently enrolled in MSc in Data Science and came across the concept of Hadoop. This interests me and I want to be good at it. I am wondering if anyone can advise me on: 1. Is it worth to have Apache Spark certification with MSc in DS? Should I invest my time in AWS or GCP certification instead? 2. Which certification is good in your opinion (data bricks or Cloudera)? 3. How long does it take someone to prepare for their exam? I only code in R.

Thanks in advance for your feedback.
