You’ve successfully deployed Hadoop, but are you taking advantage of all of Hadoop’s features to operate a stable and effective cluster? In the first part of the talk, we will cover issues that have been seen over the last two years on hundreds of production clusters with detailed breakdown covering the number of occurrences, severity, and root cause. We will cover best practices and many new tools and features in Hadoop added over the last year to help system administrators monitor, diagnose and address such incidents.

The second part of our talk discusses new features for making daily operations easier. This includes features such as ACLs for simplified permission control, snapshots for data protection and more. We will also cover tuning configuration and features that improve cluster utilization, such as short-circuit reads and datanode caching.

Hello, Shankar. Thank you for the comment.

Our presentation draws on our operations experience supporting Hortonworks Data Platform, but most of the advice is distro-agnostic. We focus on tools that are made available upstream in Apache Hadoop, so even if you’re running a different distro, I expect you’ll still find something valuable in our content.
