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? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
