@Geoffrey Shelton Okot , first thank you , you said that you prefer to do ambari-server stop instead stooping the components on the worker machine , but stooping all cluster by ambari-server stop will cause downtime on this cluster !!!, so I not feel good with this action , so stop the component only on the worker machine is less dramatic then stooping all cluster on production second , regarding to your step 3 , as I said datanode directory is configured ok , no need to change anything regarding to your step 4 , why I need to access each datanode while the problem is only on one datanode ( worker75 ) ? as you know we have 165 workers machines but only worker75 have the problem so all datanode are ok , the only problem is with one worker machine , as I mentioned sdd not created under /grid instead of that sdd created under slash , so this is the reason that we want to copy the content under /sdd to /grid/sdd ...
