What happen to cluster data incase of power outage?
These are the additional questions:
*Im running a bunch of spark jobs, does the outage will corrupt these data that are being written and read?
*Incase of NFS transfer, normally the files would be corrupted
*How to determine if these files are corrupted?
*What are the steps in order to have the cluster up and running again? (Should it be sequential or not)
*Should there be logs in case of power outage?
