             Summary: Potentially ineffective call to close() in QueryCli
                 Key: KYLIN-2050
                 URL: https://issues.apache.org/jira/browse/KYLIN-2050
             Project: Kylin
          Issue Type: Bug
            Reporter: Ted Yu
            Priority: Minor


Here is related code:
{code}
        } finally {
            if (rs != null) {
                rs.close();
            }
            if (stmt != null) {
                stmt.close();
            }
            if (conn != null) {
                conn.close();
            }
        }
{code}
If the first or second close() throws exception, the subsequent close() would be skipped.
This pattern may appear in other class(es).
