[jira] [Updated] (REEF-1765) Building a Parquet Reader for Potential Integrations with Other ML Frameworks

     [ https://issues.apache.org/jira/browse/REEF-1765?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shouheng Yi updated REEF-1765:
------------------------------
    Description: 
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
