> 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.
