Files Automatically Split

Problem

When trying to export a job, multiple files are created, even though there is no specification for splitting files. Desired outcome would be for a single file. 

Cause

This is standard behavior. By default, Hadoop will distribute the export job, resulting in split files.

Resolution

Datameer can override these settings, by entering the following parameter to your Custom Hadoop Properties:

das.splitting.max-split-count=1

Note, this may cause performance slowdowns with large exports.
