Review comment:
For example, we want to download data as csv format, we don't need to
care about the table format:
```scala
spark.table("tableName").write.format("csv").option("dateFormat",
"yyyy-MM-dd").save("/tmp/spark/download/sessionid/queryid")
```
and then download data from `"/tmp/spark/download/sessionid/queryid"`.
