TPC-DS runner did not work - ET0106 error

I tried to run the TPC-DS test mentioned in the sticky, but got errors:

This is because the TPC-DS scripts rely on creating external tables, allowing them to access the data loaded into CSV file in HDFS.

External table capability needs to be explicitly enabled in the server configuration file, as discussed in chapter 8 of the Kognitio Guide. Specifically, the configuration file needs to have "external_tables=yes" set in the [boot options] section.
