Tanuj Khurana updated PHOENIX-7701:
-----------------------------------
Description: When paging times out in UngroupedAggregateRegionScanner, the
scanner checks if it has already counted some rows. If so, it returns the
current count. If not, it returns a dummy result. As part of PHOENIX-5117 , we
mark the flag on the ScannerContext to return response to the client
immediately only for a dummy result. However, if paging timeout happens but a
valid result is returned instead, then we do not force for immediate return
currently. The fix is to set the ScannerContext in that case too. (was: When
