- Install Cloudera or Horton works Hadoop distribution. In situations where you do not have the hadoop distributions already available you can use the optional sandbox install steps install local hadoop script as described below in . See section "Sandbox Set up Hadoop Installdistribution "
Java 1.7.x or greater must be installed. Ensure JAVA_HOME environment environment variable
isexists and set
and pointsto your JDK installation.
- Download, build and install additional development tools via Additional Build Tools
- Install the following packages via yum install <package>

Compiling and Configuring Trafodion
To build and compile Trafodion
...
Set up Hadoop distribution (Install Hadoop, Hbase, Hive to local workspace)
You can use single node standalone Apache install OR use Trafodion supplied ‘install_local_hadoop’ script customized to install Cloudera distribution for a single node. When using Trafodion supplied Hadoop install script you can do the following:
Make sure you have set up password less authentication. Basically you should be able to "ssh localhost" without having to enter a password
Download latest Apache Trafodion source from Apache Incubator https://github.com/apache/incubator-trafodion
Using ssh, set Trafodion environment
...
cd incubator-trafodion
...
Configuring DCS and starting Trafodion
- Open a new terminal via ssh
- cd <apache-incubator-dir>/core/sqf . ./sqenv.
; . ./env.sh
cd $MY_SQROOT/sql/scripts
- sqgen
- sqstart (Wait till all process is up and running)
- sqcheck
sqlci > initialize trafodion;
Perform a quick sanity test of the install, by creating a sample table and querying it
- sqlci
>set schema trafodion.sch;
>create table t (a int not null, primary key(a));
>insert into t values (1), (3);
>select * from t;
>exit;
- sqlci
Edit $DCS_INSTALL_DIR/conf/dcs-site.xml and
Sandbox Hadoop install (Optional)
The instructions below describe steps to install and start sand boxed version of Hadoop using non-default ports
...
install_local_hadoop -p <port>
...
Execute the script ‘install_local_hadoop’
Note:
This script will download Hadoop and HBase jar files from the internet. To avoid this overhead for future executions of the script, you can save the downloaded files into a separate directory and set the environment variable MY_LOCAL_SW_DIST to point to that directory.
...
The files to save are: $MY_SQROOT/sql/local_hadoop/*.tar.gz $MY_SQROOT/sql/local_hadoop/tpcds/tpcds_kit.zip.

wget http://archive.apache.org/dist/hive/hive-0.13.1/apache-hive-0.13.1-bin.tar.gz
wget http://archive.apache.org/dist/hadoop/common/hadoop-2.4.0/hadoop-2.4.0-src.tar.gz
Untar the files in $HOME/tools folder
tar xzf apache-hive-0.13.1-bin.tar.gz $HOME/tools/apache-hive-0.13.1-bin
tar xzf hbase-0.98.1-cdh5.1.0.tar.gz $HOME/tools/hbase-0.98.1-cdh5.1.0

c. For Pre-installed Hadoop/HBase version, Update the HBase configuration and restart HBase.
...
‘install_local_hadoop –p rand' — will start with any random port number between 9000 and 49000
OR
‘install_local_hadoop –p < specify a port # >' — will start with port number specified
OR
‘install_local_hadoop' — will use default port numbers for all services
To start/stop/check Hadoop environment when using Trafodion supplied Hadoop install script, you can execute ‘swstartall’ , ‘swstopall’ and ‘swstatus’
For Hadoop installs that did not use Trafodion supplied Hadoop install script, please update HBase configuration as shown below and restart HBase

Alternatively, use the install_local_hadoop script. See step 3 under the "Build" heading below.
NOTE: The hadoop release contains 32-bit libraries. You must build hadoop from source for 64-bit architecture, and not just download the release tar file. See: http://wiki.apache.org/hadoop/HowToContribute

install_local_hadoop -p <start-port>
<start-port> ... <start-port>+199 should be a range of unused ports.

the components installed via Additional Build Tools
If you have not already downloaded Apache Trafodion source now you can download it from here https://github.com/apache/incubator-trafodion
Using a new ssh session, set Trafodion environment
cd incubator-trafodion
. ./env.sh
make all (Build Trafodion, DCS, REST) OR
make package (Build Trafodion, DCS, REST, Client drivers) OR
make package-all (Build Trafodion, DCS, REST, Client drivers and Tests for all components)
b. . cd $MY_SQROOT/sql/scripts
c. Execute script , ‘install_traf_components’. Based on the tar files available in the distribution folder this script will install the Trafodion components.
Note: All tar files will be created in ‘distribution’ folder located at the very top level (incubator-trafodion)
To install a custom Trafodion component you can set various environment variable to overwrite the default tar files found in distribution folder.
Environment variables supported by install_traf_component script are :
DCS_TAR — Specify the fully qualified path of DCS tar file
REST_TAR — Specify the fully qualified path of REST tar file
PHX_TAR — Specify the fully qualified path of Phoenix test tar file
CLIENT_TAR — Specify the fully qualified path of Trafodion client tar file
DCSTEST_TAR — Specify the fully qualified path of DCS tests tar file
Starting Trafodion and its components
Using a new ssh session,
cd incubator-trafodion; Execute . ./env.sh
cd $MY_SQROOT/sql/scripts
Execute the script, ‘sqgen’ and then start using the script ‘sqstart’
Note: In case of any issues and if there is a need to stop and restart a specific Trafodion component, you can use the component based start/stop scripts.
Component | Start script | Stop script |
For all of Trafodion | sqstart | sqstop |
For DCS (Database Connectivity Service) | dcsstart | dcsstop |
For REST server | reststart | reststop |
For LOB server | lobstart | lobstop |
For RMS server | rmsstart | rmsstop |
|
|
|
Checking the status of Trafodion and its components
There are several health check scripts that are available which will provide the status of Trafodion. They are :
sqcheck (For all of Trafodion)
dcscheck (For Database Connectivity Service)
rmscheck (For RMS Server)
Creating Trafodion metadata
Using a new ssh session,
cd incubator-trafodion; . ./env.sh
cd $MY_SQROOT/sql/scripts
Use sqlci (direct to sql engine) or trafci (uses DCS to connect to SQL engine)
Execute the sql initialization script via sqlci or trafci, ‘initialize trafodion’
Testing Trafodion
There are several helper scripts provided to run the tests for Trafodion components in your workspace. These scripts are generated based on the tar files that are made available during execution of install_traf_component script
swphoenix {t4 | t2 } — This script will run the Phoenix test using JDBC Type 4 driver or JDBC Type 2 driver
swjdbc — This script will run JDBC Type 4 tests
swpyodbc — This script will install Linux drivers run ODBC tests using Linux driver
