@Rachna Bakhru Please reply in comments if it is not a new answer. Here is some sample code to connect to a Kerberized cluster from JAVA program on Windows machine. Your steps should be similar. 1. Copy krb5.conf file to your Windows machine. 2. Copy different resource files to Windows. (core-site.xml,yarn-site.xml, hdfs-site.xml, hive-site.xml ) 3. create a . jaas file with following configuration. Client {
com.sun.security.auth.module.Krb5LoginModule required
useKeyTab=true
useTicketCache=false
renewTicket=true };
Change your login code as follows.
conf = new org.apache.hadoop.conf.Configuration();
try{
String principal = "<principal>";
String keytab = "<keytab location>";
conf.set("hadoop.security.authentication", "Kerberos");
conf.addResource(new Path("./core-site.xml"));
conf.addResource(new Path("./yarn-site.xml"));
conf.addResource(new Path("./hdfs-site.xml"));
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab(principal, keytab); 5. Then launch JAVA program with following parameters and specify paths for krb5.conf and .jaas file. -Djava.security.auth.login.config="path-to-jaas-file" -Djava.security.krb5.conf="path-to-krb5.conf"
