------------------------------
Summary: Rewrite backup with Procedure V2
Key: HBASE-15411
URL: https://issues.apache.org/jira/browse/HBASE-15411
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
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.
