------------------------------
Summary: Support a mechanism for running hive locally that doesnt
require having a hadoop executable.
Key: HIVE-7115
URL: https://issues.apache.org/jira/browse/HIVE-7115
Project: Hive
Issue Type: Improvement
Components: Testing Infrastructure, Tests
Reporter: jay vyas
Mapreduce has a "local" mode by default, and likewise, tools such as pig and
SOLR do as well,.... maybe we can have a first class local mode for hive also.
For local integration testing of a hadoop app, it would be nice if we could
fire up a local hive instance which didnt require "bin/hadoop" for running
local jobs. This would allow us to maintain polyglot hadoop applications much
easier by incorporating hive into the integration tests. For example:
{noformat}
LocalHiveInstance hive = new LocalHiveInstance();
hive.set("course","crochet")l
hive.runScript("hive_flow.ql")l
{noformat}
Would essentially run a local hive query which mirrors
{noformat}
hive -f hive_flow.ql -hiveconf course=crochet
{noformat{
It seems like thee might be a simple way to do this, at least for small data
sets, by putting some kind of alternative (i.e. in memory) execution
environment under hive, if one is not already underway ?
