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: library(rJava) muMstSpark <- function(mesosMaster = NULL, input = NULL, output = NULL, scalaLib = NULL, sparkCore = NULL, inputSplits = 8) { if (is.null(mesosMaster) || is.null(input) || is.null...

[PATCH] pass struct io * to io_loop_handle_add()/io_loop_handle_remove()
Hello, currently I'm working on new ioloop handler which uses epoll(4) API introduced in Linux kernel 2.6. In this API each fd added to fd set by epoll_ctl system call can be accompanied with user supplied data (integer or void pointer). epoll_wait syscall reports arrived events as an array of structures containing event mask and user d...

TDM Card loses Dialtone and Battery
Hello all, I've posted on this problem before. Well here goes again. I have an intel mobo with a p4 2.4ghz proc, 1GB Ram. It has built-in ethernet and vga and 6 pci slots. I dreamed of making this my household communications server: internet router, firewall, vpn and asterisk. Everything works except the TDM fxs card. Well it works for a little while and it dies: no dialtone, no ring tone. All 6 slots are filled: two more Ethernet cards, two digium fxo cards, an sb live card and the tdm card. Everything that I do...

Asynchronous IO
Hi, I have installed Xen on Linux 2.6.11.10 <http://2.6.11.10> and i am trying to do Asynchronous Direct IO on SAS drives.
