Thanks for clarification! How do they approach interactivity with "big data"/hadoop(Hbase I presume)? Apache Drill is still draft/wip, Impala is not that fast from what I hear (for interactive)... unless they pre-calculate some use cases, but how would that constitute (semi)real-time interaction with hadoop. MR by its nature is not very real-timey.
