问题描述

我是新手，当遇到以下两个命令时，我正在尝试使用python在sparkSql中的一些命令:

I am new to spark and was trying out a few commands in sparkSql using python when I came across these two commands:

createOrReplaceTempView ()和 registerTempTable ().

两个命令之间有什么区别?它们似乎具有相同的功能集.

What is the difference between the two commands?. They seem to have same set of functionalities.

推荐答案

registerTempTable是1.x API的一部分，在Spark 2.0中已弃用.

registerTempTable is a part of the 1.x API and has been deprecated in Spark 2.0.

createOrReplaceTempView和createTempView已在Spark 2.0中引入，以替代registerTempTable.

createOrReplaceTempView and createTempView have been introduced in Spark 2.0, as a replacement for registerTempTable.

除了功能上等效的registerTempTable和createOrReplaceTempView以外，前者称为后者.

Other than that registerTempTable and createOrReplaceTempView functionally equivalent and the former one calls the latter one.
