Ted Yu created HBASE-7501:
-----------------------------

             Summary: Introduce MetaEditor method that both adds and deletes rows in .META.
table
                 Key: HBASE-7501
                 URL: https://issues.apache.org/jira/browse/HBASE-7501
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu


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.

See https://reviews.apache.org/r/8674/
