Prepare data using Pig to processing with R

[Vinicius Brito Rocha]

Hi, 

There is a way where the prepare data fase be made using pig and just use R for start the mapreduce function? I try some tutorials in RevolutionR site, but in all of then the data is loaded in R and then transfered to Hadoop with to.dfs() function.

Thanks

I don't have a lot of experience with pig, but there is a pig.hive format that should work with either. In Hive, you'd need to work on an external table so that you know a path to it. Create and populate external table in Hive, then process in rmr2. I am not sure what the equivalent in pig would be though.
