Dmitriy Selivanov commented on SPARK-14326:
-------------------------------------------
This particular case was related to reading csv files with spark-csv package.
Of course spark-csv can infer schema, but this require 2 scans over data.
When I need int64 in R, I use bit64 package.
> Can't specify "long" type in structField
