How do I read a Parquet in R and convert it to an R DataFrame?

Question

I\'d like to process Apache Parquet files (in my case, generated in Spark) in the R programming language.

Is an R reader available? Or is work being done on one?

Answer 1

For reading a parquet file in an Amazon S3 bucket, try using s3a instead of s3n. That worked for me when reading parquet files using EMR 1.4.0, RStudio and Spark 1.5.0.
