---------------------------------

             Summary: Go thru the common code to find references to HIVE_EXECUCTION_ENGINE to make sure conditions works with Spark
                 Key: HIVE-7530
                 URL: https://issues.apache.org/jira/browse/HIVE-7530
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Xuefu Zhang


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.
