Issue with elastic search river plugin

Elastic Stack Elasticsearch
1

Hi,all

when load data to elastic search using river, I always get the error:
ClassNotFoundException.

The fellow is the error description:
The elastic search has 3 nodes,their ip is 192.168.71.234,192.168.71.235
and 192.168.71.236
First, Install the river plugin, the 3 node return right, and the
${elasticsearch.home}/plugins directory has the plugin.
Second, execute the curl command:
curl -XPUT '192.168.71.236:9201/_river/myhadoop/_meta' -d '{
"type":"hadoop",
"hadoop":{
"path":"/user/test/appinfo/2014-09-15",
},
"index":{
"index":"dmp2",
"type":"tag",
"sha":true
}
}'
Finally, i get the river status,but get error:
{
"_index" : "_river",
"_type" : "myhadoop",
"_id" : "_status",
"_version" : 1,
"found" : true,
"_source":{"error":"NoClassSettingsException[Failed to load class with
value [hadoop]]; nested: ClassNotFoundException[hadoop];
","node":{"id":"ECzwbXLPTnqP5Ch4IQTAVg","name":"node71-235-open","transport_address":"inet[localhost/192.168.71.235:9600]"}}
}

what is the problem here?

Yes you need to restart nodes when installing a 'Java' plugin.
