Apache Drill

Last week I spent some time playing with Apache Drill and I really liked it. It seems that tool had some significant development last year and the coverage of SQL functionality is wide enough to migrate from Hive (at least in many typical cases).
I had a chance to do a short introduction presentation which is available here:
Introduction to Apache Drill
It seems there are still some issues that may block introducing Drill into existing production environments.
First of all it doesn’t support YARN, so it may be a challenge to deploy it alongside existing Hadoop nodes. Missing Kerberos support may also be an issue for some mature production clusters. There are however tickets already created for both of the features, so maybe in the next versions we will enjoy those improvements.
