Hi,
I tried to run secure containers in cluster, and followed the instructions
from
http://hadoop.apache.org/docs/r2.6.0/hadoop-project-dist/hadoop-common/SecureMode.html#LinuxContainerExecutor
After that, I ran the mapreduce example pi and got the following exception:
2017-02-06 17:46:24,018 INFO

Here is the container-executor.cfg under /etc/hadoop owned by root
(configurations are same to the yarn-site.xml):
yarn.nodemanager.local-dirs=/data1/yarn/nm,/data2/yarn/nm,/data3/yarn/nm
yarn.nodemanager.log-dirs=/data1/hadoop/logs/container
yarn.nodemanager.linux-container-executor.group=hadoop
banned.users=yarn
min.user.id=500
allowed.system.users=hadoop,dm
Hope to get some helps.

Reid Chan.
