Thanks! From: Herman van Hövell tot Westerflier [mailto:hvanhov...@questtec.nl] Sent: Fri, Jun 03, 2016 10:05 To: Gerhard Fiedler <gfied...@algebraixdata.com> Cc: dev@spark.apache.org Subject: Re: Where is DataFrame.scala in 2.0?
Hi Gerhard, DataFrame and DataSet have been merged in Spark 2.0. A DataFrame is now a DataSet that contains Row objects. We still maintain a type alias for DataFrame: https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/package.scala#L45 HTH Kind regards, Herman van Hövell tot Westerflier 2016-06-03 17:01 GMT+02:00 Gerhard Fiedler <gfied...@algebraixdata.com<mailto:gfied...@algebraixdata.com>>: When I look at the sources in Github, I see DataFrame.scala at https://github.com/apache/spark/blob/branch-1.6/sql/core/src/main/scala/org/apache/spark/sql/DataFrame.scala in the 1.6 branch. But when I change the branch to branch-2.0 or master, I get a 404 error. I also can’t find the file in the directory listings, for example https://github.com/apache/spark/tree/branch-2.0/sql/core/src/main/scala/org/apache/spark/sql (for branch-2.0). It seems that quite a few APIs use the DataFrame class, even in 2.0. Can someone please point me to its location, or otherwise explain why it is not there? Thanks, Gerhard
