Subject Map Reduce Jobs With Memory Cached Tables
Date Thu, 28 Aug 2008 19:21:01 GMT
Greetings:


I have a map reduce job based on TableMap that takes a single memory cached
column on a single table as an input (all rows, of course).  What we need to
have happen is to have the system create a separate map job for each region
of the table and run in such a way that the input for the map job comes
straight out of memory instead of being streamed over the network from a
region server.

Is this possible?  How might one do this?
