Best Practices for Dynamic Partitioning in Hive

With its proven ability to speed performance, partitioning is a must-have feature in the tool set of any Big Data query engine. Hive is no exception; it has had partition support since its early versions. Although this blog will touch on static partitioning, it will primarily focus on when and how to best employ dynamic partitioning—a method we believe is often underutilized as an effective means for partitioning data and improving performance.

What’s Next for YARN and Docker

As an execution fabric for running applications, YARN faces the same software-dependency problem encountered by all operating systems—“DLL Hell” as it was once affectionately known. In one post we explained how lightweight Linux Containers combined with speedy Docker Images are a perfect way to solve this dependency problem. In another post, we highlighted some of the deficiencies of Docker for this purpose, and outlined some of the work we’ve done to integrate Docker into YARN, addressing the deficiencies along the way. It’s been a while since our last report, so we thought it was time to bring you up to date.
