Hi all,  
Am getting this exception when I'm trying to write to Elasticsearch using mapreduce program with es-hadoop. Am trying to write to _index=employee and type=basic_ which already exists in my Elasticsearch cluster.

**My stack trace :-**  
Exception in thread "main" org.elasticsearch.hadoop.EsHadoopIllegalArgumentException: No resource ['es.resource'] (index/query/location) specified

**My driver class** :-  
Configuration conf = new Configuration();  
Job job = Job.getInstance(conf, "es-hadoop");  
job.setJarByClass(DIGDriver.class);  
conf.set("es.nodes", "localhost:9200");  
conf.set("es.port", "9200");  
conf.set("es.resource", "employee/basic");  
job.setNumReduceTasks(0);  
job.setOutputFormatClass(EsOutputFormat.class);  
job.setMapperClass(DIGMapper.class);  
job.setMapOutputValueClass(MapWritable.class);  
conf.setBoolean("mapreduce.map.speculative", false);  
conf.setBoolean("mapreduce.reduce.speculative", false);  
boolean status = job.waitForCompletion(true);  
if (status) {  
System.exit(0);  
} else {  
System.out.println("Job Failed : Some error!");  
System.exit(1);  
}

Please help me on this.

You are not initializing the configuration correctly. From the javadocs (Job#getInstance):

``  
Creates a new Job with no particular Cluster and a  
given Configuration.

The Job makes a copy of the Configuration so  
that any necessary internal modifications do not reflect on the incoming  
parameter.  
``

The configuration fully before creating the job instance. Note that there are several other gotchas like this around `Configuration` so always check the javadocs and the sources.  
P.S. Formatting helps
