Supported Platforms
Red Hat or Centos 6.x (6.4 or later) versions are supported as development and production platforms.
...
Ensure that the Java environment exists and points to your JDK installation. By default Java is located in /usr/lib/java-<version>| Code Block | ||

You should export JAVA_HOME in your .bashrc or .profile file. |
Setup Passwordless SSH
You need to be able to ssh to localhost without having to specify a password. The method used to set up passwordless SSH keys depends on whether you're downloading the Trafodion source directly using hub clone.
If You're Using Hub Clone
Check to see if you have passwordless SSH setup.
| Code Block | ||||
|---|---|---|---|---|
| ||||
ssh localhost
Last login: Fri Nov 6 22:44:00 2015 from 192.168.1.9 |
If passwordless SSH is not setup, please do so now. The following is an example of setting up passwordless SSH using id_rsa keys. You can choose the method that best represents your environment.
If You've set up your ssh keys using the method described in https://github.com/settings/ssh, which means that you already have an existing set of ssh keys. Simply copy both the id_rsa and .pub and id_rsa.pub to the your ~/.ssh directory.
Then, do the following:
| Code Block | ||||
|---|---|---|---|---|
| ||||
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/id_rsa.pub
echo "NoHostAuthenticationForLocalhost=yes" >>~/.ssh/config
chmod go-w ~/.ssh/config |
If You Downloaded and Unpacked the SourceEnsure that you've set up passwordless authentication.you need to create your keys first, then do the following:
| Code Block | ||||
|---|---|---|---|---|
| ||||
ssh localhost
gtapper@localhost's password:
Last login: Fri Nov 6 22:44:00 2015 from 192.168.1.9 |
If you see the above, then setup passwordless ssh doing the following:
| Code Block | ||||
|---|---|---|---|---|
| ||||
ssh-keygen -t rsa -N "" -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/id_rsa.pub
echo "NoHostAuthenticationForLocalhost=yes" >>~/.ssh/config
chmod go-w ~/.ssh/config |
Verify Trafodion Download
Verify that the Trafodion source has been either:
- Downloaded and unpackaged.
- Cloned from github.
If not, please do so now. Refer to Contributor Workflow - Code/Docs.
Install Required Build Tools
Refer to Required Build Tools for instructions.
Verify System Limits
-keygen -t rsa -N "" -f ~/.ssh/id_rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/id_rsa.pub
echo "NoHostAuthenticationForLocalhost=yes" >>~/.ssh/config

Verify Trafodion Download
Verify that the Trafodion source has been either:
- Downloaded and unpackaged.
- Cloned from github.
If not, please do so now.
To download from github, refer to Contributor Workflow - Code/Docs.
Otherwise downloaded and untar the source tar file from Apache Trafodion Incubator release.
Install Required Build Tools
Refer to Required Build Tools for instructions.
Verify System Limits
Please check that the system limits in your environment are appropriate for Apache Trafodion. If they are not, then you will need to increase the limits Please check that the system limits in your environment are appropriate for Apache Trafodion. If they are not, then you will need to increase the limits or Trafodion cannot start.
...
Please refer to this article for information on how you change system limits.

The output should show that eight several jar files exist. The number of files differs based on the version of Trafodion you downloaded.
Setup Test Environment
You should test your installation using:
- A local Hadoop environment
- Trafodion installation
You're Your installation approach depends on whether you already have installed Hadoop.
...
| Code Block | ||||
|---|---|---|---|---|
| ||||
cd <download<Trafodion source directory>/incubator-trafodion make package |
The binary tar files will be created in <download <Trafodion source directory>/incubator-trafodion/distribution directory.
Install a Local Hadoop Environment
...
| Code Block | ||||
|---|---|---|---|---|
| ||||
# Ensure that the Trafodion environmental variables have been loaded. cd <download<Trafodion source directory>/incubator-trafodion source ./env.sh |

You need to do the following each time you download new source code.
| Code Block | ||

Assuming no errors, your installation has been successful. You can start working on your modifications.
| Note |
|---|
If you are not able to start up the environment or if there are problems running sqlci or trafci, then verify that the all the processes are up and running. swstatus should show at 6 java servers and 2 mysql processes. sqcheck should indicate all processes are running. If processes are not running as expected, please stop Trafodion by running sqstop, stop the Hadoop processes by running swstopall, then restart by running swstartall and sqstart. Sometimes Trafodion processes do not terminate cleanly, you can run ckillall to quickly terminate all Trafodion processes. If problems persist please review logs: Hadoop, HBase, and Hive logs are located in $MY_SQROOT/sql/local_hadoop/*/logs |
