Hi Nicolas Your maven command seems incomplete.
You need to navigate to the module containing the specific set of tests (typically, for unit tests in Drill souce, it is the java-exec dir). I dont think you need the 'install' phase of the lifecycle, and the 'test' phase should be sufficient. mvn test [-Dtest=<testSuiteName>] -Pmapr There are a number of tests in meach of the modules, so you could take a look at that to get an idea.

At the same time, I am implementing the writing part of the plugin, I have figured most of the components I need to implement out already. The only thing that is still a bit obscure is around BatchCreator. I have created the following class hoping it is loaded automatically somehow, but I need explanations on how that works in order to effectively attach this problem. class TableWriterBatchCreator implements BatchCreator On the test side, I need guidance on how to create and run the corresponding tests for this module.
