[system test] create index on bucket w/ incoming load is stuck.

1. drop index default.min_price_min_stop- success
2. create index again - ( There is incoming load on the bucket)
CREATE INDEX min_price_min_stop ON default((((((((`AirItinerary`.`OriginDestinationOptions`).`OriginDestinationOption`)[0]).`FlightSegment`)[0]).`DepartureAirport`).`LocationCode`),(((((((`AirItinerary`.`OriginDestinationOptions`).`OriginDestinationOption`)[0]).`FlightSegment`)[1]).`ArrivalAirport`).`LocationCode`),array_length(((((`AirItinerary`.`OriginDestinationOptions`).`OriginDestinationOption`)[0]).`FlightSegment`)),(((((`AirItineraryPricingInfo`.`PTC_FareBreakdowns`).`PTC_FareBreakdown`).`PassengerFare`).`TotalFare`).`Amount`)) USING GSI

After about an hour - I see this index is consistently at 77% complete.
