mai shurong updated YARN-5449:
------------------------------
    Description: 
The nodemanager process is hung, and lost from resourcemanager.
The nodemanager' log is stopped from printing.
The used cpu of nodemanager process is very low(nearly 0%).
GC of nodemanager jvm process is stopped, and the result of jstat(jstat 
-gccause pid 1000 100) is as follows:

The nodemanager jvm process is also accur this problem using CMS garbage 
collector or g1 garbage collector.

The parameters of CMS garbage collector are as following:
-Xmx4096m  -Xmn1024m  -XX:PermSize=128m -XX:MaxPermSize=128m 
-XX:+UseConcMarkSweepGC -XX:+CMSConcurrentMTEnabled -XX:ConcGCThreads=4 
-XX:+UseCMSCom pactAtFullCollection -XX:CMSFullGCsBeforeCompaction=8 
-XX:ParallelGCThreads=4 -XX:CMSInitiatingOccupancyFraction=70 

The parameters of g1 garbage collector are as following:
-Xmx8g -Xms8g -XX:PermSize=128m -XX:MaxPermSize=128m -XX:+UseG1GC  
-XX:MaxGCPauseMillis=1000 -XX:G1ReservePercent=30

-XX:+PrintAdaptiveSizePolicy
