How Do I Configure the knox Memory?

Log in to a Master node of the cluster as user root.
Run the following command on the Master node to open the gateway.sh file:
su omm

vim /opt/knox/bin/gateway.sh
Change APP_MEM_OPTS="" to APP_MEM_OPTS="-Xms256m -Xmx768m", save the file, and exit.
Run the following command on the Master node to restart the knox process:
sh /opt/knox/bin/gateway.sh stop

sh /opt/knox/bin/gateway.sh start
Repeat the preceding steps on each Master node.
Run the ps -ef |grep knox command to check the configured memory.
