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?
