> Components: Coprocessors
> Affects Versions: 2.0.0
> Reporter: Stephen Yuan Jiang
> Assignee: Stephen Yuan Jiang
> Priority: Minor
> Fix For: 2.0.0

>
>
> Procedure V2 replaced table DDL handler implementation to procedure
> implementation. It does not make sense to keep the *Handler methods in
> MasterObserver. This JIRA follows HBASE-13645 way to deprecate the existing
> observers with *Handler and add the new observers with more meaningful names.
>
> One proposal that to rename the coprocessor in procedure thread with Action
> and use Completed/Rollback to distinguish successful or failed procedures.
> (Note: this JIRA is just for name change; the actual Rollback cp does not
> exist today)
