1. Start a new ssh session and ensure that the Trafodion environmental variables are loaded.

   Code Block
   language bash
   cd <Trafodion source directory> source ./env.sh

   Code Block
   language bash title Example: Load Environment Variables
   cd mysource/incubator-trafodion source ./env.sh

2. Install the Hadoop software.

   Code Block
   language bash
   cd $MY_SQROOT/sql/scripts install_local_hadoop ./install_traf_components

   Code Block
   language bash title Example: Install Hadoop Software
   $ cd $MY_SQROOT/sql/scripts $ install_local_hadoop Checking for existing Hadoop processes... The testware tpcds_kit.zip does not exist and will not be installed This testware is needed to run developer HIVE regression tests . . . Installed directory size and name = 2.7G /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/sql/local_hadoop Setup is complete. You can use the convenience scripts starting with sw... located in /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/sql/scripts. $ ./install_traf_components Installing and configuring DCS, REST, TRAFCI & Phoenix tests for Trafodion... Environment used for core, DCS, REST and Phonenix ... . . . Configuration scripts for DCS, REST, TRAFCI and Phoenix test are set up Open a new session and start Trafodion by executing sqgen and sqstart scripts $

3. Verify installation.

   Code Block
   language bash
   $ swstatus 6 java servers and 2 mysqld processes are running 713 NameNode 19513 HMaster 1003 SecondaryNameNode 838 DataNode 1173 ResourceManager 1298 NodeManager

   The following Java servers should be running:

   • NodeManager (Yarn)

   • ResourceManager (Yarn)

   • NameNode (HDFS)

   • SecondaryNameNode (HDFS)

   • DataNode (HDFS)

   • HMaster (HBase)

     In addition, 2 mysqld processes should be running.

     Info
     The Hadoop enviroment is install in: $MY_SQROOT/sql/local_hadoop. The log files are located in$MY_SQROOT/sql/local_hadoop/log and in the Hadoop components' log directories. If a service is not started, then look in the associated log files for the issue and search for the error string for possible solutions to the issue; these are Hadoop issues and are therefore outside the scope of this guide.

4. Run sqgen — sqgen creates the Trafodion configuration files. Do the following:

   1. Start a new terminal window for this step.

   2. Do the following:

      Code Block
      language bash
      cd <Trafodion source directory> source ./env.sh cd $MY_SQROOT/etc # delete ms.env, if it exists rm ms.env cd $MY_SQROOT/sql/scripts sqgen

      Code Block
      language bash title Example: Run sqgen
      $ cd mysource/incubator-trafidiontrafodion $ source ./env.sh $ cd $MY_SQROOT/etc # delete ms.env, if it exists $ rm ms.env $ cd $MY_SQROOT/sql/scripts $ sqgen Workstation environment - Not a clustered environment Generating SQ environment variable file: /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/etc/ms.env Note: Using cluster.conf format type 2. . . . *********************************************************** Updating Authentication Configuration *********************************************************** Creating folders for storing certificates $

5. Start Trafodion.

   Code Block
   language bash title Example: sqstart
   $ sqstart Checking orphan processes. Removing old mpijob* files from /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/tmp Removing old monitor.port* files from /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/tmp Executing sqipcrm (output to sqipcrm.out) Starting the SQ Environment (Executing /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/sql/scripts/gomon.cold) Background SQ Startup job (pid: 15755) . . . You can monitor the SQ shell log file : /home/trafdeveloper/mysource/incubator-trafodion/core/sqf/logs/sqmon.log Startup time 0 hour(s) 0 minute(s) 59 second(s) $

6. Initialize Trafodion

The final step is to initialize the Trafodion database.

$ sqlci
Apache Trafodion Conversational Interface 1.3.0
Copyright (c) 2015 Apache Software Foundation
>>initialize trafodion;

--- SQL operation complete.
>> exit;

End of MXCI Session
