-------------------------------

             Summary: HoS should populate split related configurations to HiveConf
                 Key: HIVE-16483
                 URL: https://issues.apache.org/jira/browse/HIVE-16483
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Chao Sun
            Assignee: Chao Sun


There are several split related configurations, such as {{MAPREDMINSPLITSIZE}}, {{MAPREDMINSPLITSIZEPERNODE}},
{{MAPREDMINSPLITSIZEPERRACK}}, etc., that should be populated to HiveConf. Currently we only
do this for {{MAPREDMINSPLITSIZE}}.

Without these, Spark sometimes will not merge small files for file formats such as text.
