Subject [jira] [Commented] (ACCUMULO-391) Multi-table Accumulo input format
Date Thu, 29 Aug 2013 13:33:51 GMT

Corey J. Nolet commented on ACCUMULO-391:
-----------------------------------------

Agreed- I've got a remote branch pushed up last night with the initial patch applied as-is.
The refactor of the constants into the MetadataSchema, the removal of the ContextFactory,
and a couple other small changes broke the patch. I'm working through getting the tests running
in their current state and I'll  work through modifying the current InputFormatBase to provide
multi-table support.

> Just realized we had no MR input method which supports multiple Tables for an input format.
I would see it making the table the mapper's key and making the Key/Value a tuple, or alternatively
have the Table/Key be the key tuple and stick with Values being the value.
