             Summary: UngroupedAggregateRegionScanner doesn't release rpc 
handler on page timeouts
                 Key: PHOENIX-7701
                 URL: https://issues.apache.org/jira/browse/PHOENIX-7701
             Project: Phoenix
          Issue Type: Improvement
            Reporter: Tanuj Khurana


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|https://issues.apache.org/jira/browse/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.
