             Summary: move snapshot verification during restore / clone into the async master side handling
                 Key: HBASE-22942
                 URL: https://issues.apache.org/jira/browse/HBASE-22942
             Project: HBase
          Issue Type: Improvement
          Components: snapshots
    Affects Versions: 2.2.0, 2.1.0, 1.4.0, 1.3.0
            Reporter: Sean Busbey


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.
