Description

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:

          if (!HiveConf.getVar(job, ConfVars.HIVE_EXECUTION_ENGINE).equals("tez")
              && isEmptyPath(job, path, ctx)) {
            path = createDummyFileForEmptyPartition(path, job, work,
                 hiveScratchDir, alias, sequenceNumber++);

          }

We need to make sure the condition still holds after a new execution engine such as "spark" is introduced.
