Description

We currently have the BatchScanner, which does not guarantee in order results with the benefit of higher parallellization. Unfortunately, if you want to query multiple tables, the only option is to chain BatchScanner's together, but you lose something of the optimizations under the hood for both using system resources well as well as getting data back in order. We have another ticket for multi-table accumulo input format for mapreduce, but I would like to see a multi table version of a batch scanner for regular client use.
