Hello, I am currently encountering a problem with one nodemanager.
I used a snapshot rollback on the cluster, and since, only this nodemanager (1 of 3) is having trouble.
http://pastebin.com/wsppupBf
we can see:
chmod: changing permissions of `/var/run/cloudera-scm-agent/process/608-yarn-NODEMANAGER/container-executor.cfg': Operation not permitted
chmod: changing permissions of `/var/run/cloudera-scm-agent/process/608-yarn-NODEMANAGER/topology.map': Operation not permitted
So I tried to give the proper ownership to these files (yarn:hadoop).
But then cloudera manager recreate the configuration under
var/run/cloudera-scm-agent/process/609-yarn-NODEMANAGER/
So I had like ten folders for yarn under the cloudera agent process... I removed those but it continued to increment the number of folder as I tried to start it again.
So Cloudera manager seems to create these 2 files with root:root ownership everytime, which is weird since It shouldn't be able to do it.
I clearly don't understand what's going on here.
Any hint to help me resolve it ?
Thanks 🙂
