[jira] [Created] (CRUNCH-246) HFileSource

Chao Shi created CRUNCH-246:
-------------------------------

             Summary: HFileSource
                 Key: CRUNCH-246
                 URL: https://issues.apache.org/jira/browse/CRUNCH-246
             Project: Crunch
          Issue Type: Improvement
          Components: IO
            Reporter: Chao Shi
            Assignee: Chao Shi


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?
