Cannot load Parquet files created with parquet-cpp in Drill

[Uwe Korn]

Hello,

I'm currently looking at the correctness of our C++ implementation of 
Parquet and noticed that I cannot load these files in Drill. Although 
this is probably a bug in the C++ implementation, I don't understand 
what causes the error. Using the Java parquet-tools, I can read these 
files. I'm using Apache Drill 1.8.0 on OSX.

I've posted the error output from Drill and the parquet file as a gist: 
https://gist.github.com/xhochy/d4441a5ff2025b877df43fecd4466a11

If anyone could have a short look into this and tell me why Drill cannot 
read the file, you would really help me to fix the parquet-cpp issues.

Kind Regards,

Uwe
