-----------------------------------
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.
