I'm playing with DataFrames, but I ran into a problem:
df.createOrReplaceTempView("Table1")
df.createOrReplaceTempView("Table2")
spark.sql("SELECT * from Table1").show()
This doesn't work since I can't createOrReplaceTempView for multiple tables, is there a way to use multiple data tables for queries with DataFrames?
I have tried giving values to both tables, didn't work either.
