Hi,all:
recently,I attempted to access Kerberized hadoop cluster by launching
JAVA applications from Windows workstations. And I hava configured kerberos in
my windows7, and can successfully access hdfs50070. But when I launch JDBC from
windows to connection remote hiveserver,errors accured:
java.sql.SQLException:could not open client transport with JDBC
Uri:jdbc:hive2://hm:10000/default;principal=hive/[email protected]: GSS initiate
failed

below are my test codes:
public static void main(String[] args) {
String principal = "hive/[email protected]";
String keytab = "E:\\Program Files
(x86)\\java\\jre7\\lib\\security\\hive.keytab";
String url = "jdbc:hive2://hm:10000/default;principal=hive/[email protected]";
conf.addResource(new File("hdfs-site.xml").toURI().toURL());
conf.addResource(new File("core-site.xml").toURI().toURL());
conf.addResource(new File("yarn-site.xml").toURI().toURL());
conf.addResource(new File("hive-site.xml").toURI().toURL());
conf.set("hadoop.security.authentication", "Kerberos");
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab(principal, keytab);
Class.forName("org.apache.hive.,jdbc.HiveDriver");
Connection conn =DriverManager.getConnection(url);
Statement stmt = conn.createStatement();
String sql = "select * from testkerberos";
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
system.out.println(rs.getString(1));
}
}
Does anyone had the same problem? Or know how to solve it ?
Thanks in advance.
Maria.
