Description

Right now we do snapshot verification prior to queueing the restore / clone request from the client. That means the initial call from the client has to block until we're done. On large manifests (~single digit millions) this easily takes longer than the default timeout of 20 minutes.

 

Instead we should handle verification as one of the steps in the relevant procedure (hbase 2+) or table handler (hbase 1) so that the master can do it in the background and report status.
