  1. traf_tools_setup.sh installation: a script that uses wget to download the appropriate tar file, builds, and installs the required tool into a directory of your choice for each tool listed above.  The advantage of this method is that all the correct tools are downloaded and built in a single directory.  Before building, a single environment variable needs to be set called TOOLSDIR.  
  2. Manual installation: if one or more of these tools are already installed in your environment or if you want to verify the download location before accepting software, then you can install each tool separately.  The advantage of this method is you don't have to reinstall tools that you already have installed.  However, there may be an issue with incompatibility between the existing tools and versions required by Trafodion.  If you choose this method, you need export the following variables before building:
    export BISON="<tool location>/bison_3_linux/bin/bison"
    export LLVM="<tool location>/dest-llvm-3.2"
    export UDIS86="<tool location>/udis86-1.7.2"
    export ICU="<tool location>/icu4.4"
    export MPICH_ROOT="<tool location>/dest-mpich-3.0.4"
    export ZOOKEEPER_DIR="<tool location>/zookeeper-3.4.5"
    export THRIFT_LIB_DIR="<tool location>/thrift-0.9.0/lib"
    export THRIFT_INC_DIR="<tool location>/thrift-0.9.0/include"
    export LOG4CXX_LIB_DIR="<tool location>/apache-log4cxx-0.10.0/lib"
    export HADOOP_BLD_LIB="<tool location>/hadoop-2.6.0/lib/native"
    export HADOOP_BLD_INC="<tool location>/hadoop-2.6.0/include"
