Pentaho PDI (Kettle) - notes to self


The Pentaho download page majors on the commercial versions.
(not sure whether the Community Edition (CE) comes with the commercial version)
Scroll down to Community Projects to find the open source version.

Spoon - the GUI where one designs, develops and tests ETL graphs.
So remember to run (spoon.bat) to fire up the environment and not simply click on the "Data Integration 64-bit" application (this resulted in the necessary libext JDBC libraries not to be available and resulted in a few errors below).

Problem with MySQL connection and PDI v.4.3

Error connecting to database [mytest_mysql] : org.pentaho.di.core.exception.KettleDatabaseException: 
Error occured while trying to connect to the database
Exception while loading class
Caused by: java.lang.ClassNotFoundException:

To resolve this problem, read the issue log here which requires you download the ConnectorJ from here
$ tar xvzf mysql-connector-java-5.1.21.tar.gz mysql-connector-java-5.1.21/mysql-connector-java-5.1.21-bin.jar
$ cp -ip /downloads/mysql-connector-java-5.1.21/mysql-connector-java-5.1.21-bin.jar /usr/local/pentaho/data-integration/libext/JDBC/
