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.

Use the following command to check your system limits:

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 $MY$TRAF_SQROOTHOME/sql/scripts install_local_hadoop ./install_traf_components

   Code Block
   language bash title Example: Install Hadoop Software
   $ cd $MY$TRAF_SQROOTHOME/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-trafodion $ 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
