Stephen Yuan Jiang commented on HBASE-15411:
--------------------------------------------
Today, we directly access the {{mpmHost}} from master. I think it is
reasonable to add a accessor ('getMasterProcedureManagerHost()') to do the same
thing.
{code}
public ExecProcedureResponse execProcedure(RpcController controller,
ExecProcedureRequest request) throws ServiceException {
try {
...
ProcedureDescription desc = request.getProcedure();
MasterProcedureManager mpm = master.mpmHost.getProcedureManager(
desc.getSignature());
...
{code}
A separate JIRA just similar to MasterServices#getSnapshotManager() is good.

> 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.
