How to start hiveserver2 as service

Question

Hi all I have setup multi node cluster (i.e 5 node) in my network which working fine. now I wanted to insert and retrieve data from cluster using hive thus I have setup hive latest release apache-hive-0.14.0-bin.tar.gz (i.e. 0.14.0 from here ) on my master node as given in this article.

also I have written a java client class which will make jdbc connection to hive and insert the data into HDFS using hive.

HiveJdbcClient.Java

public class HiveJdbcClient {

private static final String DRIVER_NAME = "org.apache.hive.jdbc.HiveDriver";
    private static final String HIVE_URL = "jdbc:hive2://x.x.x.x:10000/default";
    private static final String HIVE_UNAME = "";
    private static final String HIVE_PWD = "";
    private static Connection con;

    private HiveJdbcClient() {}

    public static Connection getConnection() {
        try {
            if (con == null) {
                synchronized (HiveJdbcClient.class) {
                    if (con == null) {
                        Class.forName(DRIVER_NAME);
                        con = DriverManager.getConnection(HIVE_URL,
                                HIVE_UNAME, HIVE_PWD);
                        System.out.println("Successfuly Connected to database...!");
                    }
                }// End of synchronized block.
            }// End of if block.
        } catch (SQLException e) {
            System.out.println("Can Not able to connect to database pls check your settings \n" + e);
        } catch (ClassNotFoundException e) {
            System.out.println("Can Not able to connect to database pls check your settings \n" + e);
        }// End of try-catch block. 
        return con;
    }// End of getConnection() Method.

    public static ResultSet executeQuery(String sql) {
        ResultSet set = null;
        try {
            if (sql != null) {
                set = getConnection().createStatement().executeQuery(sql);
            }
        } catch (SQLException e) {
            System.out.println("Error while executing query " + e);
        }// End of try-catch block.
        return set;
    }// End of executeQuery() Method.

    public static void main(String[] args) throws ParseException, SQLException {
        ResultSet res = executeQuery("SELECT * FROM mytable");
        while (res.next()) {
            System.out.println(String.valueOf(res.getString(1)) + '\t'
                    + String.valueOf(res.getFloat(2)) + '\t'
                    + String.valueOf(res.getString(3)));
        }
    }
}//End of HiveJdbcClient Class.

my application able to connect to server when I run following command in terminal

$HIVE_HOME/bin/hiveserver2
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/opt/hadoop-2.6.0/share/hadoop/common/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/opt/apache-hive-0.14.0-bin/lib/hive-jdbc-0.14.0-standalone.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
OK 

but when I close this terminal then my application gives following error

ERROR

java.sql.SQLException: Could not open client transport with JDBC Uri: jdbc:hive2://X.X.X.X:10000/default: java.net.ConnectException: Connection refused

that means I have to run hiveserver2 as a service on my master node.

can any one help me to run this hiveserver2 as service. or any link which will help me to run hiveserver2 as service.

Answer 1

Have you tried --service option?

$HIVE_HOME/bin/hive --service hiveserver2 &
