Hi, even if not closely related to Hadoop-Java, Rstudio is a killer app for Data Scientists who develop R code. It's under AGPLv3 and can be executed in two modes: as an IDE (desktop-side), as a webapp (server-side). They release already .rpm packages. http://www.rstudio.com/ide/ Bye -- Daniele Medri https://twitter.com/dmedri
