----------------------------------
Summary: Evaluate CombineHiveInputFormat versus HiveInputFormat
[Spark Branch]
Key: HIVE-9153
URL: https://issues.apache.org/jira/browse/HIVE-9153
Project: Hive
Issue Type: Sub-task
Components: Spark
Affects Versions: spark-branch
Reporter: Brock Noland
The default InputFormat is {{CombineHiveInputFormat}} and thus HOS uses this.
However, Tez uses {{HiveInputFormat}}. Since tasks are relatively cheap in
Spark, it might make sense for us to use {{HiveInputFormat}} as well. We should
evaluate this on a query which has many input splits such as {{select count(*)
from store_sales where something is not null}}.
