connect to hive from R

Question

I need to process data stored on Hadoop in R (some clustering, and statistic). I used Hive to analysis data previously. I found JDBC package for R and would like to use it. However, it doesn't works, it seems a lot of jars are not available. Could you provide a good instruction or tutorial? How to query data from Hive in R?

Answer 1

you were need to copy Hive's jars to your R classpath and load them to RJDBC. You can read details with sample in my blog here http://simpletoad.blogspot.com/2013/12/r-connection-to-hive.html

Answer 2
