-------------------------------
I got the following when running test suite with patch v2:

> Backport HBASE-4552 to 0.90 branch.
> -----------------------------------
>
> Key: HBASE-4718
> URL: https://issues.apache.org/jira/browse/HBASE-4718
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.90.4
> Reporter: Jonathan Hsieh
> Assignee: Jonathan Hsieh
> Attachments: 4718-v2.90, hbase-4718.0.90.patch,
> hbase-4718.v3.includes-hbase-3316.patch
>
>
> In discussion of HBASE-4552 / HBASE-4677 there has been some discussion about
> whether and how to backport HBASE-4552 to the 0.90 branch. This is a
> potentially compatibility breaking so several approaches hav ebeen suggested.
> 1) provide patch but do not integrate
> 2) integrate patch that extends and deprecates old api without removing old
> api. It has been argued that clients are supposed to use
> LoadIncrementalHFiles api and not at the internal HRegionServer RPC api.
