Security issue while writing data to HBase table from SPARK using Java - apache-spark

Question

JavaDStream<FreshInput> inputDStream = kafkaInputDStream
.map(new Function<Tuple2<String, FreshInput>, FreshInput>() {
private static final long serialVersionUID = 1L;
#Override
public FreshInput call(Tuple2<String, FreshInput> tuple) throws Exception {
if(tuple._2!=null)
{
FreshLogger.errorLog_and_Console("***************************************************");
FreshLogger.errorLog_and_Console("INSIDE FRESH INPUT CALL");
FreshLogger.errorLog_and_Console(tuple._1.toString());
FreshLogger.errorLog_and_Console(tuple._2.toString());
FreshLogger.errorLog_and_Console("***************************************************");
Configuration hconf=HBaseConfiguration.create();
hconf.addResource(new Path("/etc/hbase/conf/core-site.xml"));
hconf.addResource(new Path("/etc/hbase/conf/hbase-site.xml"));
UserGroupInformation.setConfiguration(hconf);
FreshLogger.errorLog_and_Console("hconf is "+hconf.toString());
//UserGroupInformation.loginUserFromKeytabAndReturnUGI("gffshnee", "/etc/krb5.keytab");
Connection connection = ConnectionFactory.createConnection(hconf);
Table table = connection.getTable(TableName.valueOf("gfttsdgn:FRESHHBaseRushi"));
Put p = new Put(Bytes.toBytes("row1"));
p.add(Bytes.toBytes("c1"), Bytes.toBytes("output"), Bytes.toBytes("rushi"));
table.put(p);
}
return tuple._2();
}
});
Getting following Exception:
2017-02-24 09:09:33 WARN -FRESH Executor task launch worker-0 -UserGroupInformation : PriviledgedActionException as:gffshnee (auth:SIMPLE) cause:javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]
