The Trafodion sandbox is a virtual appliance that provides a simulation of Trafodion on a single-node cluster, giving you an area where you can become familiar with Trafodion. Download the trafodion_release.ova file and install it on a PC that is already running one of the supported hypervisors. The sandbox already has Trafodion Release 1.1 and Hortonworks Data Platform (HDP) installed.

NOTE: If you encounter problems or need assistance with the installation or use of the Trafodion sandbox, please email tbd for help.

Checking System Resources

To run the Trafodion sandbox successfully, you will need at least 16 GB of memory on your PC. The sandbox uses about 5 GB of memory while the Hadoop services and Trafodion are running, so make sure that you have enough available memory on your PC to support those processes. Otherwise, the sandbox will operate very slowly.

Your PC should have virtualization enabled in its BIOS settings. To enable virtualization on your PC, follow these steps:

1. Power off your PC.
2. When powering on your PC, press Esc to display the Startup Menu.
3. When the Startup Menu appears, press F10 for BIOS Setup.
4. In the BIOS Setup, select the System Configuration tab.
5. Select Device Configurations.
6. Scroll down and select Virtualization Technology.
7. Click Save.
8. When prompted to save changes, click Yes.
9. Click Exit.
10. When prompted again to save changes, click Yes.
11. Restart your PC.

Installing the Trafodion Sandbox

...

1. Once you are logged in to the virtual machine, start the Hadoop services:
   1. Click the Firefox browser icon in the toolbar and enter sandbox:8080 (or localhost:8080) in the address bar to open the Ambari console.
   2. In the Ambari console, enter admin for the username and admin for the password, and click Sign in.
   3. All Ambari services should be started (green).
   • If they are not, in the left side of the console, click Actions and select Start All.
   • When prompted for confirmation, click OK. This will start the Hadoop services. Please note that it might take a while for all the Hadoop services to start, especially if your system has limited memory. (See thethe recommended system resources.)
   • If all the Hadoop services start up successfully, you will see a green check mark next to Start All Services, and its progress bar will be green at 100%. Please allow some time for all the services to be active and in a steady state. Once the services appear to be running, proceed to step 9.
   • If you see a red exclamation point next to Start All Services or a red exclamation point next to one or more services, click on each of the stopped services and manually try to start each one. (See step 10 for a list of the required Hadoop services.) Once you have manually started the services, proceed to step 9.

   NOTE: If any problems arise while you are starting the Hadoop services, see the Troubleshooting section.

2. The HBase service might show a green check mark even when the HBase Master is not live. To check that the HBase Master is live, click the HBase service in the left pane of the Dashboard tab. If it shows that the HBase Master is not live, click Restart the HBase Master. Once the HBase Master is live, proceed to step 10.
3. In the Ambari Dashboard, verify that these required Hadoop services continue to be in the Started state:
   • HDFS
   • MapReduce2
   • HBase
   • Hive
   • WebHCat
   • ZooKeeper
   If any of those services have stopped, restart them.
4. Check the actual status of HBase by starting a terminal session (by selecting Applications > System Tools > Terminal from the toolbar) and running the HBase shell command called status 'detailed':

   [trafodion@trafodion ~]$ hbase shell
   
   hbase(main):001:0>status 'detailed' 
   version 0.98.0.2.1.7.0-784-hadoop2
   0 regionsInTransition
   master coprocessors: []
   1 live servers
       trafodion.local:60020 1423613814142
           ...
   0 dead servers
   
   hbase(main):003:0>
   

   If there are no live HBase RegionServers, return to step 9 to restart those servers. If the HBase RegionServers are live, proceed to step 12.
