Ted Yu commented on HBASE-15584:
--------------------------------
Suppose the procID / backupID mapping is written in the hbase:backup table
first, after that RPC call returns to the client.
This would endure the loss of RPC, right ?
> Revisit handling of BackupState#CANCELLED

> Key: HBASE-15584
> URL: https://issues.apache.org/jira/browse/HBASE-15584
> Project: HBase
> Issue Type: Sub-task
> Reporter: Ted Yu
> Priority: Minor
>
> During review of HBASE-15411, Enis made the following point:
> {code}
> nobody puts the backup in cancelled state. setCancelled() is not used. So if
> I abort a backup, who writes to the system table the new state?
> Not sure whether this is a phase 1 patch issue or due to this patch. We can
> open a new jira and address it there if you do not want to do it in this
> patch.
> Also maybe this should be named ABORTED rather than CANCELLED.
> {code}
> This issue is to decide whether this state should be kept (e.g. through
> notification from procedure V2 framework in response to abortion).
> If it is to be kept, the state should be renamed ABORTED.
