      Question:
      Hive port is closed

      Description:
      I want to launch Hive queries remotely.

      For that, I am using the hive-jdbc library (0.14.0 version) and hadoop-core (1.2.1 version).

      Some weeks ago, I launch the following code:

      try

      { Class.forName("org.apache.hadoop.hive.jdbc.HiveDriver"); }

      catch (ClassNotFoundException e)

      { e.printStackTrace(); System.exit(1); }

      Connection con = DriverManager.getConnection(
      "jdbc:hive://cosmos.lab.fi-ware.org:10000/default", "user",
      "password");
      Statement stmt = con.createStatement();
      String sql = "select * from table_name";
      ResultSet res = stmt.executeQuery(sql);
      while (res.next())

      { System.out.println("value: " + res.getString(1)); }

      and it works, but now I am getting this error:

      java.sql.SQLException: Could not establish connection to cosmos.lab.fi-ware.org:10000/default: java.net.ConnectException: Conexión rehusada
      at org.apache.hadoop.hive.jdbc.HiveConnection.<init>(HiveConnection.java:117)
      at org.apache.hadoop.hive.jdbc.HiveDriver.connect(HiveDriver.java:107)
      at java.sql.DriverManager.getConnection(DriverManager.java:571)
      at java.sql.DriverManager.getConnection(DriverManager.java:215)

      I saw that now the Hive port (10000) is closed.

      So, I am wondering what is the correct way to use a remote hive client to access to cosmos, or If I have to change the way to get data from cosmos.
