> The bug is in {{ParquetRecordReaderWrapper}}. We store metastore such as the
> list of columns in the {{Configuration/JobConf}}. The issue is that this
> metadata is incorrect until the call to
> {{projectionPusher.pushProjectionsAndFilters}}. In the current codebase we
> don't use the configuration object returned from
> {{projectionPusher.pushProjectionsAndFilters}} in other sections of code such
> as creation and initialization of {{realReader}}. The end result is that
> parquet is given an empty read schema and returns all nulls. Since the join
> key is null, no records are joined.
