Ted Yu commented on HBASE-15411:
--------------------------------
In test run of TestFullBackup#testFullBackupSingle, even though snapshot
succeeded:
{code}
2016-03-10 20:33:13,000 DEBUG [B.defaultRpcServer.handler=1,queue=0,port=56481]
snapshot.SnapshotManager(359): Snapshot '{
ss=snapshot_1457670792650_default_test-1457670784996 table=test-1457670784996
type=FLUSH }' has completed, notifying client.
{code}
there was no occurrence of the following log at the beginning of state 3 (test
finished soon after taking snapshot):
{code}
case SNAPSHOT_COPY:
// do snapshot copy
LOG.debug("snapshot copy");
{code}
Tried moving snapshot action into FullTableBackupProcedure - result was the
same.
> 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.
