Bootstrap.mlockall: true in elastisearch not take effect?

Hi, as es official web site stated, it is strongly recommend that bootstrap.mlockall: true should be set in elasticsearch.yaml file. but after restart es, I find that the setting is not effective as below graph

es is restarted with an user rui rather than root, I doubt that rui has no permission to make bootstrap.mlockall: true to take effect. So what I can do with that?

Any help will be appreciated!

Thanks a lot in advance

Where did you set it? Did you set heap min/max the same?

I set the property in elasticsearch.yml as below graph

For heap, I set the envrionment ES_HEAP_SIZE=3g.
And I start ES by the user rui with Supervisord

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them.

Hi warkolm,I set the property in /opt/modules/elasticsearch-2.3.3/conf/elasticsearch.yml as bootstrap.mlockall: true, and restart es via supervisord, the conf of which is as
command=/opt/modules/elasticsearch-2.3.3/bin/elasticsearch 0. 0.0.0
but after restarting, I see the below result in _nodes/process?pretty:

"M_r6PeG4TraVpfUeoZnmOA" : {
"name" : "node-2",
"transport_address" : "",
"host" : "",
"ip" : "",
"version" : "2.3.3",
"build" : "218bdf1",
"http_address" : "",
"process" : {
"refresh_interval_in_millis" : 1000,
"id" : 10305,
"mlockall" : false
I want to ask why?

Thanks a lot!
