Hi Team,

I had setup elasticsearch cluster(version 6.8.14) using eck operator. I wanted to use more heapsize so I had set ES\_JAVA\_OPTS as "-Xms6g -Xmx6g". but it is taking the default heapsize which is 1g. Kindly help me here.

output of ps -ef | grep java

Hi,

Could you share the YAML manifest that you use to deploy Elasticsearch?
