             Summary: Early connection close to release server resources during 
creating
                 Key: HIVE-24694
                 URL: https://issues.apache.org/jira/browse/HIVE-24694
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
            Reporter: Zhihua Deng
            Assignee: Zhihua Deng


If exception happens during we try to get the connection from HiveDriver,  the 
opened transport or session may leave unclosed as the connection returned is 
null, we cannot call the close method to release the server 
resources(threads/connection quota), this could make things more worse if the 
user rearches the connection limit,  the following calls to get the connection 
will be failed until we restart the hs2.
