I specified my IP address as network.host in elasticsearch.yml:

# grep ^network.host elasticsearch.yml
network.host: 64.237.55.66

[2016-11-26T23:54:20,084][ERROR][o.e.b.Bootstrap ] [FCEKEaM] node validation exception
bootstrap checks failed initial heap size [1610612736] not equal to maximum heap size [25763512320]; this can cause resize pauses and prevents mlockall from locking the entire heap

Please advise.
