Hi, Recently I was looking into the issue of PXF receiving multiple REST requests to the fragmenter. Based on offline discussions I have got a rough idea that this is happening because HAWQ plans every query twice on the master. I understand that this is to allow resource negotiation that was a feature of HAWQ 2.0. I'd like to know if anyone on the mailing list can give any more background into the history of the decision making behind this change for HAWQ 2.0 and whether this is only a short term solution
Thanks, Kavinder
