Chao Shi updated CRUNCH-246:
----------------------------
Attachment: crunch-246.patch
Thanks Ryan. My first attempt is attached. It only includes thin wrapper
HFileSource, based on Ryan's HFileInputFormat (change the input key from
ImmutableBytesWritable to NullWritable, to fit crunch's PCollection), and it
does not support materialization.

> 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
> different).
> 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?
