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.
