Subject MR Data Locality with AccumuloInputFormat?
Date Fri, 16 May 2014 17:32:29 GMT
Hi, folks,

When I execute an MR job with AccumuloInputFormat, are there any guarantees
about which mappers process which rows? I'm trying to minimize crosstalk in
my cluster but either I haven't split my table properly or I'm expecting
too much, because I'm only seeing 1 or 2 nodes running MR tasks that should
be reading data from tablet servers on 8 different nodes.
