Hi,
I did enabled the vmem check. But what I really want to know is that why huge
virtual memory(17.9 GB) used when JVM option -XX:+PrintGCDetails was added.
The appliction which I run was hadoop jar hadoop-mapreduce-examples-2.7.2.jar
pi -D mapreduce.map.java.opts=-XX:+PrintGCDetails 5 100
ubject: Yarn container use huge virtual memory with JVM option
-XX:+PrintGCDetails added.
Hi All,
I’m currently running Hadoop 2.7.2 on my three node cluster, all node equiped
with 32-core CPU and 64 GB memory, Ubuntu 14.04.3 LTS. Yarn’s configuration
kept the same with default one,
am really confused why huge virtual memory allcated when JVM option
-XX:+PrintGCDetails was added. Please help!
Thank You,
JR

"mapred.child.java.opts" in the mapred-site.xml
