ClassNotFoundException when running distributed job using rJava package
Hi,
I have a MapReduce Java code, which I am calling from R using rJava. I have
prepared the R package and tested that successfully. But when I deployed
the package in a cluster and executed it, I am getting
ClassNotFoundException. If I run the same job directly without integrating
with R, it runs perfectly.
Here is my R code:

Intermittent connectivity issues for JDBC / Oracle
I have been experiencing issues with an R script hanging when connecting to

R GUI installation on Linux/SuSE 10.3
After a long sufferance I had succeeded in installing R GUI on my
Linux/SuSE system. It worked fine.
Unluckily a system upgrade patch messed up my monitor so I had to reinstall
SuSE 10.3 and every other application on top of it.
I have R running back with text interface. I tried to get the nice R GUI up
& running again. I followed all the steps to reinstall the R GUI but this

Discussion starter for package level Connection API
Thought I'd try and start a discussion. Feel free to jump in.
I guess R needs to strike the right balance between opening up the
internals to package writers and not allowing them to do bad things. My
first attempt at cracking this nut is to just memcpy() the Rconnection
and not allow access to the private stuff:
/* Alternative to allowing C code access to connection API. */

We defined a C fonction called "getzlibsock" which is dedicated to

socket connections. This function is using the R internal C function
called "getConnection(int)" in order to get information about the socket

isOpen on closed connections
As far as I can tell, 'isOpen' cannot return FALSE in the case when 'rw = ""'.
If the connection has already been closed by 'close' or some other function,
then isOpen will produce an error. The problem is that when isOpen calls
'getConnection', the connection cannot be found and 'getConnection' produces an
error. The check to see if it is
