Hi all, As I noticed, VXQuery is using the main *incubator-asterixdb-hyracks* [1] project (0.2.17-incubating) while AsterixDB has an *inbuilt hyracks version* [2] (stable release 0.3.1). Out of these two, *hyracks-http* is from AsterixDB's inbuilt hyracks version [3] (Main hyracks project doesn't have hyracks-http module) and is available in maven repository [4]. I assumed this isn't an issue and moved on. However, I would like to know what do you think on this?
