This would be useful.
Please go ahead with rebase.

> Key: HBASE-11409
> URL: https://issues.apache.org/jira/browse/HBASE-11409
> Project: HBase
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: churro morales
> Assignee: churro morales
> Attachments: HBASE-11409.patch

>
> Use case:
> We were trying to combine two very large tables into a single table. Thus we
> ran jobs in one datacenter that populated certain column families and another
> datacenter which populated other column families. Took a snapshot and
> exported them to their respective datacenters. Wanted to simply take the
> hdfs restored snapshot and use LoadIncremental to merge the data.
> It would be nice to add support where we could run LoadIncremental on a
> directory where the depth of store files is something other than two (current
> behavior).
> With snapshots it would be nice if you could pass a restored hdfs snapshot's
> directory and have the tool run.
> I am attaching a patch where I parameterize the bulkLoad timeout as well as
> the default store file depth.
