Ted Yu commented on HBASE-15411:
--------------------------------
One comment is for not going through Connection when doing snapshot.
Here is code from MasterRpcServices#snapshot() :
{code}
master.snapshotManager.takeSnapshot(snapshot);
{code}
Option is for HMaster to pass snapshotManager to FullTableBackupProcedure.
I want to confirm this is acceptable.
Otherwise, suggestion for other approach is welcome.
> Rewrite backup with Procedure V2

> Currently full / incremental backup is driven by BackupHandler (see call()
> method for flow).
> This issue is to rewrite the flow using Procedure V2.
> States (enum) for full / incremental backup would be introduced in
> Backup.proto which correspond to the steps performed in BackupHandler#call().
> executeFromState() would pace the backup based on the current state.
> serializeStateData() / deserializeStateData() would be used to persist state
> into procedure WAL.
