> 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}}.
> All the others, if not set, will be using the default value, which is 1.
> Without these, Spark sometimes will not merge small files for file formats such as text.
