Subject Hive sample test
Date Tue, 05 Mar 2013 18:45:29 GMT

I was wondering if there is a way to quick-verify a Hive query before it is
run against a big dataset? The tables I am querying against have millions
of records, and I'd like to verify my Hive query before I run it against
all records.

Is there a way to test the query against a small subset of the data,
without going into full MapReduce? As silly as this sounds, is there a way
to MapReduce without the overhead of MapReduce? That way I can check my
query is doing what I want before I run it against all records.
