On the Ambari Server host, edit the ambari-env.sh file:vi /var/lib/ambari-server/ambari-env.sh2. For the AMBARI_JVM_ARGS variable, replace the default -Xmx2048m with thefollowing:-Xmx4096m -XX:PermSize=256m -XX:MaxPermSize=256m3. Restart Ambari Server for this change to take effect.ambari-server restart
