I assume 2GB is per node. Isn't this too
or a while. Is it possible to set some sort of timeout for
acquiring executors otherwise kill application?

practice to handle partitions in dataframes with a lots of columns?
Should i repartition manually after adding columns? What’s better
faster: Applying 30 transformers for each numeric column or combine
these columns to 1 vector column and apply 1 transformer?

downloading them first to hdfs?. Something like this:
sc.textFile(
http://azuremlsampleexperiments.blob.core.windows.net/criteo/day_{0-23}.gz;),
so it will have 24 partitions.
