    Description

      Hi Team;

      When I use kylin jdbc, I find that jdbc throws NoHttpResponseException.
      Then I do jdbc test cases in "DriverTest.java", I use one jdbc connection query 20 times, each time first wait 20 minutes. Unfortunately´╝î I also find that jdbc also throws NoHttpResponseException.

      This is my test code:

      try {
      for (int j = 0; j < 20; j++)

      { Thread.sleep(1000*20); Statement state = conn.createStatement(); ResultSet resultSet = state.executeQuery("select count(*) from KYLIN_SALES ;"); printResultSetMetaData(resultSet); printResultSet(resultSet); resultSet.close(); }

      } catch (InterruptedException e)

      { e.printStackTrace(); }

      This is NoHttpResponseException:

      java.sql.SQLException: Error while executing SQL "select count from KYLIN_SALES ;": java.sql.SQLException: org.apache.http.NoHttpResponseException: The target server failed to respond
