> It would be nice if we could configure the Parquet buffer size when using Parquet format for ML model import/export.  Currently, for some models (trees and ensembles), the schema has 13+ columns.  With a default buffer size of 128MB (I think), that puts the allocated buffer way over the default memory made available by run-example.  Because of this problem, users have to use spark-submit and explicitly use a larger amount of memory in order to run some ML examples.
> Is there a simple way to specify {{parquet.block.size}}?  I'm not familiar with this part of SparkSQL.
