Hi Chhaya,
Please find below sample code .
System.setProperty("java.security.krb5.conf",
"D:\\data\\Desktop\\cluster-test\\krb5.conf<file:///\\data\Desktop\cluster-test\krb5.conf>");
// Login using keytab if have access to keytab. else
UserGroupInformation.loginUserFromKeytab("hdfs/[email protected]<mailto:hdfs/[email protected]>",
"
D:\\data\\Desktop\\cluster-test\\conf\\hdfs.keytab<file:///\\data\Desktop\cluster-test\conf\hdfs.keytab>");
Note: Above 2 lines should be at the beginning in your application.

Hi Chhaya,
You can use the UserGroupInformation class from org.apache.hadoop.security
package.
Specifically following 2 methods of that class
UserGroupInformation.setConfiguration(hdfsConfiguration);
UserGroupInformation.loginUserFromKeytab(principal, keytabPath);
