\*Hello Team,
I am a student and I am learning about elasticsearch now. I find a plugin
called elasticsearch-hadoop in Github site and want to achieve a small demo
program, but I have a trouble. I describe it as follows:\*
1. elasticsearch cluster:
• one node with five shards
• start it as service
$ bin/service/elasticsearch start
Starting Elasticsearch...
ElasticSearch is already running.
• install the head plugin and can see the message as follows

1. hadoop environment:
• pseudo mode
• configuration like this
$ vim hdfs-site.xml

```
$ vim mapred-site.xml
$ vim conf/core-site.xml
```

1. eclipse environment
• Create map/reduce project
[https://lh5.googleusercontent.com/-QjXwjyjGknk/UZ2nSHjvuSI/AAAAAAAAACo/ulTZlCutgME/s1600/image6.jpg](https://lh5.googleusercontent.com/-QjXwjyjGknk/UZ2nSHjvuSI/AAAAAAAAACo/ulTZlCutgME/s1600/image6.jpg)
• add elasticsearch-hadoop plugin
• java code
[https://lh5.googleusercontent.com/-0b04R2lu0J8/UZ2n4kARMrI/AAAAAAAAADA/8zvCgk0\_nsw/s1600/image8.jpg](https://lh5.googleusercontent.com/-0b04R2lu0J8/UZ2n4kARMrI/AAAAAAAAADA/8zvCgk0_nsw/s1600/image8.jpg)
• error message
[https://lh5.googleusercontent.com/-2k3oPuIk-rc/UZ2oLmsdFZI/AAAAAAAAADI/hmql0XBGuqA/s1600/image9.jpg](https://lh5.googleusercontent.com/-2k3oPuIk-rc/UZ2oLmsdFZI/AAAAAAAAADI/hmql0XBGuqA/s1600/image9.jpg)
• full message which caused issue I think
java.lang.IllegalStateException: [GET] on
[twitter/tweet/\_search?routing=kimchy&search\_type=scan&scroll=10m&size=50preference=\_shards:0;\_only\_node:DxFg8q1XTkS5QGahzS4Vng]
failed; server[[http://xxx.xxx.xxx.xxx:9200](http://xxx.xxx.xxx.xxx:9200)] returned
[{"error":"SearchPhaseExecutionException[Failed to execute phase [initial],
No indices / shards to search on, requested indices are
[twitter]]","status":500}]
In the full message, why there are "&" in query string? I think it caused
500 status return, so the error message occurs. I typed the URL into
browser and returned same status(500).

\*
Which step is wrong? What need I do? I am very troubled about this... \*
