Data frames or Spark sql for partitioned tables
Hi,
I am new to spark and trying to implement the solution without using hive. We are migrating to new environment where hive is not present intead I need to use spark to output files.
I look at case class and maximum number of columns I can use is 22 but I have 180 columns . In this scenario what is best approach to use spark sql or data frame without hive.
Thanks,
Azmath

are you referring to data frame after map? You can use the following for
columns
.toDF("name1", "name2"....) after the map.
