设置JVM启动时的堆内存(Heap)的大小 -Xmx For setting the maximum heap size. 设置堆内存(Heap)的最大值 -Xmn 设置Young Gen 内存区的大小 -XX:PermGen 设置Perm Gen 内存的初始大小 -XX:MaxPermGen 设置Perm Gen 内存的最大值 -XX:SurvivorRatio ...
So, I tried setting _JAVA_OPTIONS to -Xmx1024m and it still fails. As a test I ran "java -Xmx1024m -version" from the command line and it fails too. If I run "java -Xmx512m -version" it succeeds. It's almost as if I can't set the max heap size to anything above 700MB....

I have reset the values for YARN's Java Heap Size of NodeManager and Java Heap Size of ResourceManager,via CM. Then I restared the cluster. <Q1> Under what file (xml, sh, map, py) do these parameters exist?? (When I look, after the cluster restarted, under the /etc/hadoop/conf....
seeJ2SE 5.0 Monitoring Tools. The maximum heap size should be determined based on the process data model (32-bit or 64-bit) and availability of virtual and physical memory on the system. Excessive use of physical memory for Java heap may cause paging of virtual memory to disk during garbage...
