      Description

      I have zookeeper installed and I'm running a single drillbit.

      I'm running a simple Jdbc program that uses drill-jdbc-all, and I do get the following error when trying to connect:

      Exception in thread "main" java.lang.NoClassDefFoundError: oadd/org/codehaus/jackson/map/ObjectMapper

      Using jdbc-all built right before DRILL-3589 commit works fine, so the problem seem to be related to the changes in DRILL-3589

      Here is the program I'm running:

      import java.sql.Connection;
      import java.sql.DriverManager;
      import java.sql.ResultSet;
      import java.sql.Statement;
      
      public class SimpleJdbc {
      
        public static void main(String[] args) throws Exception {
          Class.forName("org.apache.drill.jdbc.Driver").newInstance();
          Connection conn = DriverManager.getConnection("jdbc:drill:");
      
          Statement stmt = null;
          ResultSet rs = null;
      
          try {
            stmt = conn.createStatement();
            rs = stmt.executeQuery("SELECT employee_id FROM cp.`employee.json`");
      
            while (rs.next()) {
              System.out.println(rs.getObject(1));
            }
      
          } finally {
            if (stmt != null) {
              stmt.close();
            }
            if (rs != null) {
              rs.close();
            }
      
            conn.close();
          }
        }
      }
