Description
Hi, I am running the mnist example on a free databricks account and I cannot get a valid bundle file for the pipeline. The code runs without any errors but the zip file is empty. Switching to a directory based serialization does seem to produce a valid export of the pipeline. The Databricks cluster is Spark 2.2.0, scala 2.11. What am I doing wrong? Thanks
Attached is the bundle zip file I get.

Research direction
Start with the MNIST example and reproduce the empty bundle on the stated Spark 2.2.0 and Scala 2.11 Databricks setup. Compare its zip-based serialization with the directory-based export described in the issue; done means identifying the cause and documenting a verified resolution.
