   > Why is this closed? I recently encountered two problems using jdbc to 
connect to impala. One scenario is that the interval between two batches of 
data exceeds FETCH_ROWS_TIMEOUT_MS, and one scenario is that the row size 
exceeds MAX_ROW_SIZE.
   
   This PR is automatically closed by the PR stale checker for no recent 
activity within some time. From my understanding, exceeding the 
FETCH_ROWS_TIMEOUT_MS(I'm not sure Hive JDBC uses this) or MAX_ROW_SIZE should 
not affect the rows returned, the issue here is that the HiveServer2 always 
sets the `hasMoreRows` to false:
   
https://github.com/apache/hive/blob/master/service/src/java/org/apache/hive/service/cli/thrift/ThriftCLIService.java#L905,
   it could be a problem when the client determines whether the stream reaches 
its end or not by this variable.
