R Integration with IBM Open Platform ( IBM Hadoop and Spark Platform ) on IBM OpenPOWER

What is BigR ?

   -> Functional Programming Language
   -> End-to-End integration with R Lang and BigInsights
   -> Both R and BigR can be used in an R Env.
   -> Features available in R
           -> Explore data sets
           -> create visualizations
           -> build predictive models

Installing BigR Services -> Pre-Requisite

      -> IOP must be installed already
      -> All IOP nodes should have same version of OpenJDK
      -> All hosts should be listed in "/etc/hosts" file on each node
      -> Add umask 022 in the .bashrc file of the root user on all nodes. This action makes the file permission executable by all users. 
      -> rhel-7-for-power-le-supplementary-rpms and rhel-7-for-power-le-optional-rpms in the  /etc/yum.repos.d/redhat.repo file on all nodes. To do this, change 'enabled = 0' to 'enabled = 1'.
      -> Ensure that yum-config-manager is installed. It is included with the yum-utensils package
                    yum install -y yum-utils
      -> R Packages should be installed already as pre-requisite for BigR

Installing R Packages -> Pre-Requisite(All Nodes in the Cluster)

   -> Location of R-Package for Redhat 7.1 PPC64LE
   R-3.2.2  : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-3.2.2-1.ael7b.ppc64le.rpm
   R-core-3.2.2 : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-core-3.2.2-1.ael7b.ppc64le.rpm    
   R-java-3.2.2 : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-java-3.2.2-1.ael7b.ppc64le.rpm
   libRmath-3.2.2 : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/libRmath-3.2.2-1.ael7b.ppc64le.rpm   
   R-devel-3.2.2  : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-devel-3.2.2-1.ael7b.ppc64le.rpm  
   R-core-devel-3.2.2  : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-core-devel-3.2.2-1.ael7b.ppc64le.rpm    
   R-java-devel-3.2.2  : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/R-java-devel-3.2.2-1.ael7b.ppc64le.rpm  
   libRmath-static-3.2.2  : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/libRmath-static-3.2.2-1.ael7b.ppc64le.rpm  
   libRmath-devel-3.2.2 : ftp://ftp.software.ibm.com/linux/rpms/redhat/7.1/libRmath-devel-3.2.2-1.ael7b.ppc64le.rpm

   -> Installing "R" packages
       go to the "R" packages downloaded rpms directory
       rpm -ivh *.rpm
   -> Test R installation : Issue command "R" and that should bring up R shell prompt

Obtaining IBM BigInsights for Data Scientist Software Version 4.1

   -> Fetch below s/w from IBM Software Access Catalog ( For Development only )       
          IBM BigInsights Data Scientist 4.1.0.2 for Linux on Power English (CN87MEN )       
          ( This will download the binary file "bds-1.1.0.2.el7.ppc64le.bin" ) 
          This module contains the Big SQL, BigSheets, Text Analytics, Big R, and the BigInsights Home services
   -> Run the bin file ( after setting the appropriate execute permissions )
   -> Accept the license agreement ( Reply yes | y to continue with the install )
   -> Choose install option : Preferred is Option #2 ( Sample output shown below ) 
       -> Option #1 : If node is internet connected
       -> Option #2 : If node is not internet connected
              [root@mgt1 ~]# chmod +x bds-1.1.0.2.el7.ppc64le.bin
              [root@mgt1 ~]# ./bds-1.1.0.2.el7.ppc64le.bin
              Creating directory ./BigInsights
              Verifying archive integrity... All good.
