Hi,
When we configure memory in yarn-site.xml, we find a
recommend in hortonworks website.
Determine HDP Memory Configuration Settings
http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_installing_manual
ly_book/content/determine-hdp-memory-config.html
python yarn-utils.py -c 16 -m 64 -d 4 -k True
my question is that, for first parameter is the
-c CORES
The number of cores on each host.
How to calculate the number of cores on each host?
Use nproc? Or other tools?
I know that our host's physical cores is 8, logical cores is
32.
I should use which number? 32 or 8?
Best Regards,
Evan Yao
