How can I know specified JVM heap space (HADOOP_NFS3_OPTS) from attached string?

[#1]

HADOOP_NFS3_OPTS="-Xmx{{nfsgateway_heapsize}}m -Dhadoop.security.logger=ERROR,DRFAS ${HADOOP_NFS3_OPTS}"

[#2 · Accepted solution]

@Jorge Luis Hernandez Olmos, Ambari refers to another properties value called "NFSGateway maximum Java heap size"

If you want to change the heap size, You'd need to update "NFSGateway maximum Java heap size".
