Hello. Default setting elastic listen 127.0.0.1:9200. I need that elastic listen all network interfaces - 0 0.0.0.0:9200
If I set network.host: "0.0.0.0" in /etc/elasticsearch/elaticsearch.yml, I have the next error:
> Exception
> java.lang.IllegalStateException: failed to obtain node locks, tried [[/opt/2tb/elasticsearch/data/elasticsearch]] with lock id [0]; maybe these locations are not writable or multiple nodes were started without increasing [node.max\_local\_storage\_nodes] (was [1])?
How I can set listen 0 0.0.0.0:9200 ?
My elastic version 5.1.1 and I have 1 node

You have already a node running probably.
Check with `ps -ef` and kill the running node then restart.

Ok. You right! But I have the next:
> node validation exception
> bootstrap checks failed
> initial heap size [34359738368] not equal to maximum heap size [68719476736]; this can cause resize pauses and prevents mlockall from locking the entire heap
