Hadoop Tutorials

Hey All,

What's the best Hadoop tutorial you've used? Here are some from IBM:

    Hi Serena,

    Is it possible to install and use extra R packages in Ad hoc R script to run an application?

    Thanks in advance,

    Yes, it is possible to install and use extra R packages through Ad hoc R script application. Here is how:
    # create a local dir path for R packages
    system("mkdir /home/biblumix/R")

    # install the packages
    install.packages(pkgs="e1071", repos="http://cran.rstudio.com", lib="/home/biblumix/R")

    # add the dir path to the R libpath
    .libPaths(c(.libPaths(), "/home/biblumix/R"))

    # load the package
    library(e1071)
    ?svm

    Thanks.
