--------------------------------------------

yeah, you are right, this is only for DDL; DML probably would use a different naming convention.

> 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)
