Hi @Nawaz,

 

Check out Node Manager logs and look for WARN message similar to below :

 

WARN org.apache.hadoop.yarn.server.nodemanager.DirectoryCollection: Directory /var/log/hadoop-yarn/container error, used space above threshold of 90.0%, removing from list of valid directories 

 This will give you more insights and reason why you are getting those health alerts and take corrective action.
