Xuefu Zhang commented on HIVE-9153:
-----------------------------------
Re: Utilities.getBaseWork() changes, I suppose Rui is probably trying to clean
up some redundant (useless) code. The changed code would be equivalent to the
old one if "name" is the full path of the plan file on HDFS for non-local mode,
which is very possible but needs to be confirmed.
> Evaluate CombineHiveInputFormat versus HiveInputFormat [Spark Branch]

> 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}}.
