当我尝试使用带有es-hadoop的mapreduce程序写入Elasticsearch时,会出现此异常。我试图写信给我的Elasticsearch集群中已存在的 index = employee和type = basic 。
我的堆栈跟踪: -
线程“main”中的异常 org.elasticsearch.hadoop.EsHadoopIllegalArgumentException:没有资源 指定的['es.resource'](索引/查询/位置) org.elasticsearch.hadoop.util.Assert.hasText(Assert.java:30)at org.elasticsearch.hadoop.mr.EsOutputFormat.init(EsOutputFormat.java:257) 在 org.elasticsearch.hadoop.mr.EsOutputFormat.checkOutputSpecs(EsOutputFormat.java:233) 在 org.apache.hadoop.mapreduce.JobSubmitter.checkSpecs(JobSubmitter.java:266) 在 org.apache.hadoop.mapreduce.JobSubmitter.submitJobInternal(JobSubmitter.java:139) 在org.apache.hadoop.mapreduce.Job $ 10.run(Job.java:1290)at at org.apache.hadoop.mapreduce.Job $ 10.run(Job.java:1287)at at java.security.AccessController.doPrivileged(Native Method)at javax.security.auth.Subject.doAs(Subject.java:422)at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657) 在org.apache.hadoop.mapreduce.Job.submit(Job.java:1287)at org.apache.hadoop.mapreduce.Job.waitForCompletion(Job.java:1308)at at com.mstack.mapreduce.DIGDriver.main(DIGDriver.java:22)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) 在 sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) 在java.lang.reflect.Method.invoke(Method.java:497)at 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);
}
答案 0 :(得分:1)
通过更改配置解决了自己: -
conf.set("es.nodes", "localhost");
conf.set("es.port", "9200");
