If you’re running HBase in production, you have to be aware of many things. In this talk we will share our experience in running and operating an HBase production cluster for a customer. To avoid common pitfalls, we’ll discuss problems and challenges we’ve faced as well as practical solutions (real-world techniques) for repair.
Even though HBase provides internal tools for diagnosing issues and for repair, running a healthy cluster can still be challenging for an administrator. We'll cover some background on these tools as well as on HBase internals such as compaction, region splits and their distribution.
We'll also introduce our tool to visualize region sizing and distribution in the cluster, that we recently open sourced.
