Subject [jira] Commented: (PIG-1777) LoadFunc in a scripting language
Date Thu, 23 Dec 2010 18:40:45 GMT

    [ https://issues.apache.org/jira/browse/PIG-1777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12974690#action_12974690
] 

Alan Gates commented on PIG-1777:
---------------------------------

The change to work for a generic InputFormat instead of just sequence files is to have your
loader take its InputFormat as a constructor argument instead hard coding it.  While in general
InputFormats are not required to return Writables I think it would be ok to say that an InputFormat
used with this loader should return both Writable key and value.  

The next step for this will be to add a reference implementation and tesst.  A unit test that
implements a loader in a scripting language would be fine.
