Subject Re: Rows missing after new node bootstrapped
Date Tue, 16 Nov 2010 17:58:14 GMT
I'm pretty sure that "reading an index" and "using pig" are not
compatible right now.  the m/r support that pig builds on always does
sequential-scan range queries.

can you see the missing rows if you do a normal get_slice query for it
without pig?
