Unfortunately, export of the measurement-lab tables is not supported right 
now--they're a special kind of table hosted by BigQuery for certain projects at 
Google.

We should probably improve the error message, but export of these tables is 
unlikely to ever be supported. Instead, we'd like to migrate them to "native" 
BigQuery tables.

What do you suggest as automated way of processing a sample of 
measurement-lab:m_lab.2015_* data?

Should I schedule BQ SELECT query over m_lab data with my own table as a 
destination and export it? Or Dataflows?

Yes, if you run a query over the table with "allow large results" _disabled_, 
you will generate a native BQ table that can then be exported. That's pretty 
much the only way to get data out of an M-Lab table.
