I am new to Pentaho. I am trying to read data from MongoDB using Pentaho Data Integration Community Edition. While trying to execute the MongoDB input step, I am getting the authentication failed error. I found that, the error was due to the missing MongoDb driver in PDI.
Later, I have downloaded the mongodb-driver-3.2.2.jar file and added it to the location E:\pdi-ce-6.0.1.0-386\data-integration\lib. But still the problem persists.
While trying to get the Dbs by providing the MongoDb connection details in Pentaho MongoDb Input step, I am getting the error java.nullpointerException.
Could someone please let me know what am I doing wrong here?
