Chao Shi commented on CRUNCH-246:
---------------------------------
Just a quick update: I'm still working on this. I'd like to introduce an
method: HFileUtils#scanHFiles(Pipeline, Path, Scan). A user can specify the
scan criteria (e.g. start/stop rows). we can I will post a patch here in a few
days.

> I found this useful when directly perform MR on HFiles. I used it yesterday
> when copying a bunch of HFiles to another cluster (where the region layout is

> There is no HFileInputFormat provided by HBase, but I found the following
> from google:

> http://blog.csdn.net/kirayuan/article/details/7794402 (Java version of the
> above. The webpage is in chinese, but you can see the code)
> I'm not sure if we copy their code directly (copyright issue?). Anyone knows?
