Re: run rstdio and hadoop 1.2.1 problem.

[Antonio Piccolboni]

I don't see any RHadoop package mentioned here, so I need to ask you to either formulate your question like a problem report or find a different forum for your question. We don't support Rstdio, Hadoop or R here, even if they come up in relation to RHadoop. This is not a general forum for R and Hadoop users. Thanks
