    My concern with this is that Parquet is typically used for high performance 
OLAP queries, and changing it to JSON makes it much slower.  Out of curiosity, 
I have used Parquet with Thrift, and I know it supports Avro, is JSON a 
separate path?
    
    I'm probably going to publish a blog post on Parquet, Thrift, and Spark 
soon.
