Use the following tips to help with troubleshooting:

One way to isolate problems to Datameer X or Hadoop is to test using a local Hadoop cluster. (Click the Admin tab at the top of the page and choose Hadoop Cluster from the list on the left).
Test new workbooks with smaller amounts of data before scaling up.
Review logs/conductor.log (or click the Admin tab and look at the logs).
Tweak parameters (per job or cluster-wide) from with Datameer X by clicking the Admin tab and editing the Hadoop cluster settings.
If you encounter errors when running a job, from the Job Run Details page, click Report an issue and fill out the bug report form.

More troubleshooting tips are available on Datameer's Knowledge Base.
