Getting ready to build

Once you have your Linux system ready with sufficient disk space and Internet connection, go ahead and install the following software:

• Git to checkout the source code
• The recent update of JDK 1.6
• Recent version of make
• Asciidoc version 8.6 or above
• Apache Ant 1.7 or above
• Findbugs version 1.3.9 or above
• Latest Eclipse IDE (or your IDE/Editor of choice)

Building the Sources

To get the source code, checkout the subversion "trunk" using the following command:

...

Once these definitions are generated, you can import them in Eclipse as an existing project.

Running Tests

Running unit tests

Sqoop source code contains many unit tests that exercise its functionality. These tests can be run simply by using the following command:

ant test

Create third-party lib directory

Create a directory somewhere convenient on your development system. This directory will hold all the JDBC drivers that the tests will use. Once created, create (or edit) the build.properties file in Sqoop workspace root directory and set the the full path of this directory as the value of the property sqoop.thirdparty.lib.dir. For example:

sqoop.thirdparty.lib.dir=/opt/ws/3rd-party-lib

Setting up and running third-party tests

Third-party tests are end-to-end integration tests that exercise the basic Sqoop functionality against third-party databases. You should run these tests in order to rule out regression when testing any changes to the core system. Before you run these tests, you must setup the following databases:

Setting up MySQL

• Install MySQL version 5.1.x with necessary client tools. You can install the server in a different host than your development host if necessary. However, you must have the client tools available on your development host including the JDBC driver, and batch utilities such as mysqldump and mysqlimport.
• Place the JDBC driver in the third-party lib directory that you created earlier.

• The location of MySQL server is specified in the build.properties file by the value for the property sqoop.test.mysql.connectstring.host_url. This property defaults to jdbc:mysql://localhost/ which assumes local installation and default port setup. If however your MySQL server is installed on a different host or on a different port you should specify it explicitly as follows:

  Code Block
  sqoop.test.mysql.connectstring.host_url=jdbc:mysql://<mysqlhost>:<port>/

• In order to run the MySQL third-party tests, you would need to configure the database as follows:

  Code Block
  $ mysql -u root -p mysql> CREATE DATABASE sqooppasstest; mysql> CREATE DATABASE sqooptestdb; mysql> use mysql; mysql> GRANT ALL PRIVILEGES on sqooppasstest.* TO 'sqooptest'@'localhost' IDENTIFIED BY '12345'; mysql> GRANT ALL PRIVILEGES ON sqooptestdb.* TO 'yourusername'@'localhost'; mysql> flush privileges; mysql> \q

• Note:
  • If the installation of MySQL server is on a different host, you must replace the localhost with the appropriate client host value.
  • You should replace yourusername with your actual user name before issuing the command.

Setting up PostgreSQL

• Install PostgreSQL 8.3.9 or later along with client tools. You can install the server in a different host than your development host if necessary. However, you must have the client tools available on your development host including the JDBC driver and command line utility psql.
• Place the JDBC driver in the third-party lib directory that you created earlier.

• The location of PostgreSQL server is specified in the build.properties file by the value for the property sqoop.test.postgresql.connectstring.host_url. This property defaults to jdbc:postgresql://localhost/ which assumes local installation and default port setup. If however your PostgreSQL server is installed on a different host or on a different port you should specify it explicitly as follows:

  Code Block
  sqoop.test.postgresql.connectstring.host_url=jdbc:postgresql://<pgsqlhost>:<pgsqlport>/

• In order to run PostgreSQL third-party tests, you would need to configure the database as follows:

  • Edit the pg_hba.conf file and setup the authentication scheme to allow for testing. In a secured environment, it may be easy to setup up full trust based access by adding the following lines in this file, and commenting out any other lines referencing 127.0.0.1 or ::1.

    Code Block
    local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust

  • Also in the file postgresql.conf uncomment the line that starts with listen_addresses and set its value to '*' as follows:

    Code Block
    listen_addresses = '*'

  • Restart your PostgreSQL server after modifying the configuration files above.

  • Create the necessary user and database for Sqoop testing as follows:

    Code Block
    $ sudo -u postgres psql -U postgres template1 template1=> CREATE USER sqooptest; template1=> CREATE DATABASE sqooptest; template1=> GRANT ALL ON DATABASE sqooptest TO sqooptest; tempalte1=> \q $

Setting up Oracle

• Install Oracle 10.2.x or later and download the corresponding JDBC driver.
• Place the JDBC driver in the third-party lib directory that you created earlier.

• The location of Oracle server is specified in the build.properties file by the value for the property sqoop.test.oracle.connectstring. This property defaults to jdbc:oracle:thin:@//localhost/xe which assumes local installation and default port setup. If however your Oracle server is installed on a different host or on a different port you should specify it explicitly as follows:

  Code Block
  sqoop.test.oracle.connectstring=jdbc:oracle:thin:@//<oraclehost>:<port>/<sid>

• In order to run Oracle third-party tests, you would need to configure the database as follows:

  Code Block
  $ sqlplus system/<password>@<sid> SQL> CREATE USER SQOOPTEST identified by 12345; SQL> GRANT CONNECT, RESOURCE to SQOOPTEST; SQL> CREATE USER SQOOPTEST2 identified by ABCDEF; SQL> GRANT CONNECT, RESOURCE to SQOOPTEST2; SQL> exit $

• Note: If you are using Oracle XE and see an error like ORA-12516, TNS:listener could not find available handler with matching protocol stack, you are likely running into connection exhaustion problem. To circumvent this, log into the Oracle server as SYSTEM, run the command below and restart your server.

  Code Block
  $ sqlplus system/<password>@<sid> SQL> ALTER SYSTEM SET processes=200 scope=spfile; SQL> exit $

Running third-party tests

Once you have installed and configured all the above databases - MySQL, PostgreSQL and Oracle, you are now ready to run the third-party tests. To run them issue the following command:

$ ant test -Dthirdparty=true

Setting up and running manual tests

Certain third-party tests are categorized as Manual tests since these were introduced at a later stage and adding them to the third-party suite of tests would have resulted in ever test environment requiring new database installation.

Setting up SQL Server

• Install SQL Server Express 2008 R2 or above.
• Download and place the JDBC driver in the third-party lib directory that you created earlier.

• The location of SQL server is specified in the build.properties file by the value for the property sqoop.test.sqlserver.connectstring.host_url. This property defaults to jdbc:sqlserver://sqlserverhost:1433 which assumes installation on a host called sqlserverhost and port 1433 setup. If however your SQL server is installed on a different host or on a different port you should specify it explicitly as follows:

  Code Block
  sqoop.test.sqlserver.connectstring.host_url=jdbc:sqlserver://<sqlserverhost>:<port>

• In order to run SQL server manual tests, you would need to configure the database as follows:
  • Create a database called SQOOPTEST.
  • Create a login with name SQOOPUSER and password PASSWORD.
  • Grant all access for database SQOOPTEST to the login SQOOPUSER.

Setting up DB2 Server

• Install DB2 9.74 Express C.
• Download and place the JDBC driver in the third-party lib directory that you created earlier.

• The location of DB2 server is specified in the build.properties file by the value for the property sqoop.test.db2.connectstring.host_url. This property defaults to jdbc:db2://db2host:50000 which assumes installation on a host called db2host and port 50000 setup. If however your DB2 server is installed on a different host or on a different port you should specify it explicitly as follows:

  Code Block
  sqoop.test.db2.connectstring.host_url=jdbc:db2://<db2host>:<port>

• In order to run DB2 server manual tests, you would need to configure the database as follows:
  • Create a database called SQOOP.
  • Create a username sqoop with password PASSWORD.
  • Grant all access for database SQOOP to login sqoop.

...

• sqoop.test.db2.connectstring.database for database
• sqoop.test.db2.connectstring.username for username
• sqoop.test.db2.connectstring.password for password

Running manual tests

Once you have installed and configured all the above databases - SQL Server and DB2, you are now ready to run the manual tests. To run them, issue the following command:

$ ant test -Dmanual=true
