-------------------------------------
Summary: Allow Hive to Submit MapReduce jobs via the MapReduce API
(instead of using Hadoop BIN)
Key: HIVE-3574
URL: https://issues.apache.org/jira/browse/HIVE-3574
Project: Hive
Issue Type: Improvement
Components: Query Processor, SQL
Affects Versions: 0.9.0, 0.8.1, 0.8.0, 0.7.1, 0.7.0, 0.6.0, 0.5.0, 0.4.1,
0.4.0, 0.3.0, 0.10.0, 0.9.1
Environment: All environments would be affected by this
Reporter: Jeremy A. Lucas
Priority: Minor
Having Hive to submit generated jobs to an M/R cluster via the MapReduce API
would allow for potentially greater compatibility across platforms, in addition
to allowing for these jobs to be run easily against pseudo-clusters in tests
(think MiniMRCluster).
This kind of change could involve something as simple as using a Hadoop
Configuration object with a generic ToolRunner or something similar to run jobs.
Specifically, this kind of change would most likely occur in the execute()
method of org.apache.hadoop.hive.ql.exec.MapRedTask (note that this class
already has access to a JobConf object as well, which could serve in itself as
a Configuration object).
