Hi there,

Recently i have built elasticsearch with fluentd and Kibana and all is working fine, but we are facing high cpu load while performing search caused by java.

I have 60 GB Ram and 16 processors and each processor has 2 cores.

ES\_HEAP\_SIZE=32g  
-find below more details

curl "localhost:9200/\_cat/thread\_pool?v&h=search.rejected"  
search.rejected  
387

curl "localhost:9200/\_cat/thread\_pool?v&h=index.rejected"  
index.rejected  
0

- snapshot from elasticsearch.log

[DEBUG][action.search.type] [Hulk 2099] [logstash-2015.03.14][4], node[qxcAN3lURs65Lf1GMhB\_qg], [P], s[STARTED]: Failed to execute [org.elasticsearch.action.search.SearchRequest@7c71025f] lastShard [true]

Now i read that i have to update the threadpool settings in ES and i have now  
curl -XGET localhost:9200/\_cluster/settings?pretty  
{  
"persistent" : { },  
"transient" : { }  
}

i'm trying to update the settings with the below commands

curl -XPUT localhost:9200/\_cluster/settings -d '{

"threadpool" : {  
"index": {  
"type": "fixed",  
"size": 32,  
"queue\_size": 1000  
},  
"bulk": {  
"type": "fixed",  
"size": 32,  
"queue\_size": 1000  
},  
"search": {  
"type": "fixed",  
"size": 96,  
"queue\_size": 1000  
}  
}  
}'

but i keep getting {"error":"ActionRequestValidationException[Validation Failed: 1: no settings to update;]","status":400}

What's wrong with this command? is it the right solution for my issue ?

Please advise

Thanks.

Ayman
