> Deprecate registerTempTable and add dataset.createTempView
> ----------------------------------------------------------
>
> Key: SPARK-15171
> URL: https://issues.apache.org/jira/browse/SPARK-15171
> Project: Spark
> Issue Type: Bug
> Reporter: Sean Zhong
> Priority: Minor
>
> Our current dataset.registerTempTable does not actually materialize data. So,
> it should be considered as creating a temp view. We can deprecate it and
> create a new method called dataset.createTempView(replaceIfExists: Boolean).
> The default value of replaceIfExists should be false. For registerTempTable,
> it will call dataset.createTempView(replaceIfExists = true).
