Subject [jira] [Commented] (HBASE-15584) Revisit handling of BackupState#CANCELLED
Date Wed, 01 Jun 2016 17:56:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15584?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15310758#comment-15310758
] 

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 ?

> 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.
