    Default

    Is your Hadoop configuration set to "mapr"? To check (and change if necessary), edit data-integration/plugins/pentaho-big-data-plugin/plugin.properties and make sure the "active.hadoop.configuration" property is set to "mapr". If you have to change it, restart Spoon.

    If this doesn't fix your issue, please paste in the full stack trace and I will take a look
