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())
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.
