before I set -xmx 2g, but hiveserver throws many exception OOM. so I reset and
at the end I set xmx=15g, newRatio=1. Because I watch hiveserver for a long
time.It use memory very large when running job, usually it can be 8g ,10g,or
15g. so I set xmx=15g ,and newRatio=1 , the young generation wil
is the files you said the files from runned jobs of our system? and them
can't be so much large.
why is the cause of namenode. what are hiveserver doing when it use so large
memory?
how do you use hive? our method using hiveserver is correct?
Thanks.
