Hi, I'm a beginner in elasticsearch. I'm using also ubuntu for elasticsearch(version 1.1.0). My issue : where should I set the ES\_MIN/MAX\_SIZE(= ES\_HEAP\_SIZE)? In /etc/elasticsearch/elasticsearch.yml or /etc/default/elasticsearch or /etc/init.d/elasticsearch? From what i read i should set the ES\_MIN/MAX\_SIZE = ram / 2. My application is reading data from a Sqs and pushing it to elasticseach. This is done from 2 consumers each with a thread pool of 5 threads. That means 10 threads who are inserting documents in elasticsearch. I have a separate server for elasticsearch with 8gb of ram. From my configuration : I set ES\_MIN/MAX\_SIZE = 4g(=ram / 2) only in /etc/elasticsearch/elasticsearch.yml and restarting the elasticsearch. When I call the htop, I see for elasticsearch user the next command which is duplicated(..10 threads =\> more line like this one) : /usr/lib/jvm/java-7-openjdk-amd64//bin/java -Xms256m -Xmx1g -Xss256k -Djava.awt. Shouldn't it be -Xms2g -Xmx2g, because I set in elasticsearch.yml 2g? 1. From what i read in other posts I should set this in "service wrapper configuration". But which file is linked to "service wrapper configuration" /etc/default/elasticsearch or /etc/init.d/elasticsearch? 2. Should I have same values in elasticsearch.yml ES\_MIN\_MEM/ES\_MAX\_MEM like in "service wrapper configuration" (ES\_HEAP\_SIZE) ? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
