Celebrate failure(s) – a real-world Hadoop example (HDFS issues)

| Posted in Failures, Troubleshooting |

At Spotify, we have a company-wide culture of celebrating successes and … failures. Because we want to iterate fast, we do realize that failures can happen. On the other hand, we can not afford to make the same mistake more than once. One way of preventing from that is sharing our failures, mistakes and learning across the company.

Today however, I would like to share my failures … outside of the company ;) While my failures relate to my recent work with Apache Hadoop cluster, I think that the lessons that I have learned are generic enough, so that many people can benefit from them.
