> In common code, such as Utilities.java, I found a lot of references to this conf variable
and special handling to a specific engine such as following:
> {code}
>           if (!HiveConf.getVar(job, ConfVars.HIVE_EXECUTION_ENGINE).equals("tez")
>               && isEmptyPath(job, path, ctx)) {
>             path = createDummyFileForEmptyPartition(path, job, work,
>                  hiveScratchDir, alias, sequenceNumber++);
>           }
> {code}
> We need to make sure the condition still holds after a new execution engine such as "spark"
is introduced.
