Description

ParquetRecordReaderWrapper is reading the file footer to create the splits, but then when calling the realReader.initialize(), the file footer is read again by parquet.

The issue ~~PARQUET-139~~ did work to avoid reading the footers in parquet-avro. We should implement the same idea in Hive, and update the parquet library to the latest stable version from upstream.
