Jonathan Hsieh commented on HBASE-8465:
---------------------------------------

First can we give the jira a more descriptive title?  'Improvement' is vague 
and subjective -- this is new semantics and not some sort of speed or resource 
usage improvement.  Maybe something like "restore rollback auto-drop"?

* Does it make more sense to make this a runtime restore snapshot parameter 
instead of a xml configuration option?   (the \-for\-rollback addition only 
makes sense for the proposed style).

> Below is an excerpt from snapshot restore javadoc:
> {code}
>    * Restore the specified snapshot on the original table. (The table must be 
> disabled)
>    * Before restoring the table, a new snapshot with the current table state 
> is created.
>    * In case of failure, the table will be rolled back to the its original 
> state.
> {code}
> We can improve the handling of rollbackSnapshot in two ways:
> 1. give better name to the rollbackSnapshot (adding 
> {code}'-for-rollback-'{code}). Currently the name is of the form:
>     String rollbackSnapshot = snapshotName + "-" + 
> EnvironmentEdgeManager.currentTimeMillis();
> 2. drop rollbackSnapshot at the end of restoreSnapshot() if the restore is 
> successful. We can introduce new config param, named 
> 'hbase.snapshot.restore.drop.rollback', to keep compatibility with current 
> behavior.
