使用es-hadoop写入elasticsearch时的问题

Question

当我试图用es的mapreduce程序写到Elasticsearch时，我得到了这个异常。我试图写信给index=employee和type=basic，它们已经存在于我的Elasticsearch集群中。

我的堆栈追踪:-

线程“主”org.elasticsearch.hadoop.EsHadoopIllegalArgumentException:中的异常没有在org.elasticsearch.hadoop.util.Assert.hasText(Assert.java:30) at org.elasticsearch.hadoop.mr.EsOutputFormat.init(EsOutputFormat.java:257) at org.elasticsearch.hadoop.mr.EsOutputFormat.checkOutputSpecs(EsOutputFormat.java:233) at org.apache.hadoop.mapreduce.JobSubmitter.checkSpecs(JobSubmitter.java:266) at org.apache.hadoop.mapreduce.JobSubmitter上指定的资源'es.resource'org.apache.hadoop.mapreduce.Job$10.run(Job.java:1290) at org.apache.hadoop.mapreduce.Job$10.run(Job.java:1287) at java.security.AccessController.doPrivileged(Native Method，javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657) at org.apache.hadoop.mapreduce.在org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1308) at com.mstack.mapreduce.DIGDriver.main(DIGDriver.java:22) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)在sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497)在org.apache.hadoop.util.RunJar.run(RunJar.java:221) at org.apache.hadoop.util.RunJar.main(RunJar.java:136)

驱动程序类:-

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);
}

通过改变自己的吐露决定:-

conf.set("es.nodes", "localhost");
conf.set("es.port", "9200");
