DataFrame.scala
athttps://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
