Subject Re: question about preserving data locality in MapReduce with Yarn
Date Tue, 29 Oct 2013 02:09:44 GMT
Well, I thought an application master can somewhat ask where the data exist
to a namenode.... isn't it true? If it does not know where the data reside,
does a MapReduce application master specify the resource name as "*" which
means data locality might not be preserved at all? thx,
