Prepare the Test Environment

It is recommended that you test Trafodion by setting up a local version of Hadoop and installing Trafodion on top.  This is enabled by running the 'install_local_hadoop' script.

Run install_local_hadoop

You should test your installation using:

• A local Hadoop environment
• Trafodion installation

You're installation approach depends on whether you already have installed Hadoop.

If Hadoop is Already Installed

Build binary tar files and then install Trafodion following instructions described in Installation.

cd <download directory>/incubator-trafodion
make package

The binary tar files will be created in <download directory>/incubator-trafodion/distribution directory. 

Install a Local Hadoop Environment

The install_local_hadoop script This section describes the steps to use the Trafodion installation script called 'install_local_hadoop' that downloads compatible versions of Hadoop, HBase, Hive, and MySql and MySQL. Then, it starts Trafodion.If you started a new ssh session, be sure to
   cd <download directory>/apache-trafodion-1.3.0-incubating
   source .

# Ensure that the Trafodion environmental variables have been loaded.
cd <download directory>/incubator-trafodion
source ./env.sh

Make sure you have You need to ensure that you've set up password less authentication. You should be able to "ssh localhost" without having to enter a password.  To setup passwordless authentication:         ssh-keygen -t rsa -N "" -f $HOMEpasswordless authentication.

ssh localhost

Verify installation.

Six java servers and two mysqld processes should be running.

Verify that the install completed by running the following command - should report: 6 java servers and 2 mysqld processes are running

    swstatus

Note: 

The 'install_local_hadoop' script downloads Hadoop, HBase, Hive, and MySql jar files from the internet. To avoid this overhead, you can download the required files into a separate directory and set the environment variable MY_LOCAL_SW_DIST to point to this directory.

...

To start/stop/check Hadoop environment using Trafodion supplied scripts, you can execute  ‘swstartall’ ,  ‘swstopall’ and ‘swstatus’, and if you need to remove the installation, execute the 'swuninstall_local_hadoop'.
