Automated Spark application tuning

  • Talk in Russian

Valeria will talk about the Hadoop cluster, where hundreds of daily and thousands of hourly Spark calculations run. All the calculations are very different and have their own SLA. In this situation, it's unrealistic to tune in-house with engineers. That's why they built and implemented a fully automatic tuning system based on the logs Spark writes itself. Valeria will show you how to easily extract a lot of information from these logs in the offline mode and what to look for when automatically tuning spark.executor.memory. She will also explain in detail how their tuning system is set up and what allows them to constantly adjust for changes. The talk will be of interest to those who already deal with Spark and have an idea of its structure.
