So the patch should be ready for integration ?

>                 URL: https://issues.apache.org/jira/browse/HBASE-7501
>             Project: HBase
>          Issue Type: Bug
>            Reporter: Ted Yu
>            Assignee: Matteo Bertozzi
>             Fix For: 0.96.0
>         Attachments: HBASE-7501-v0.patch, HBASE-7501-v1.patch
> In review of HBASE-7365, MetaEditor.deleteRegions() and MetaEditor.addRegionsToMeta()
are used in RestoreSnapshotHandler.java.handleTableOperation() to apply changes to .META.
> I made following suggestion:
> Can we introduce new method in MetaEditor which takes List of Mutation's ?
> The Delete and Put would be grouped and then written to .META. table in one transaction.
> Jon responded:
> I like that idea -- then the todo/warning or follow on could refer to that method.  When
we fix it, it could get used in other multi row meta modifications like splits and table creation/deletion
in general.
