Shouheng Yi commented on REEF-1765:
-----------------------------------

[~markus.weimer] Haven't had any responses from the dev list about updating Avro version.
I moved the ParquetReader to {{reef-experimental}} according to our previous discussion. It
is in the same PR. Let me know if there is any feedback. Thanks.

> Parquet file format is very common in some well-known frameworks like Hadoop and Spark.
By enabling REEF to read parquet file, we could potentially integrate with those frameworks.
Currently we want to only support data of non-nested types with a table-like property. This
allows us to transform the data into formats like RDDs, etc.
> A draft of ParquetReader is provided here in a PR: https://github.com/apache/reef/pull/1283
