Impala v Hive | Cloudera VISION

Cloudera's Mike Olson shares perspectives on SQL-on-Hadoop market dynamics
"I get asked all the time about Cloudera’s decision to develop Impala from the ground up as a new project, rather than improving the existing Apache Hive project. If there’s existing code, the thinking goes, surely it’s best to start there — right?
Well, no. We thought long and hard about it, and we concluded that the best thing to do was to create a new open source project, designed on different principles from Hive. Impala is that system. Our experiences over the last year increase our conviction on that strategy.
Let me walk you through our thinking."
