We have a MapR 3 node cluster, Where sometimes it shows NodeManager down alarm and also attaching screenshots of it. Please help me with this issue. And also attaching Logs screenshot too.
Is this something you can help to diagnose? Thank you very much!
I'd start by looking through the yarn-mapr-nodemanager... files in the logs directory. Look for events around the time the alarm was generated, and look for anything that indicates an error or failure.
Thank you for the reply Deborah, I will start looking over it.
