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

    [ https://issues.apache.org/jira/browse/CRUNCH-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13731604#comment-13731604 ] 

Josh Wills commented on CRUNCH-246:
-----------------------------------

I don't think we can just copy it, but I'd be happy to reach out to Leif and see if he would be okay with contributing it to the project. Otherwise, we should just write our own impl.

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

> I'm not sure if we copy their code directly (copyright issue?). Anyone knows?
