[jira] [Created] (HIVE-9670) Avoid reading file footers in ParquetRecordReaderWrapper

Sergio Peña created HIVE-9670:
---------------------------------

             Summary: Avoid reading file footers in ParquetRecordReaderWrapper
                 Key: HIVE-9670
                 URL: https://issues.apache.org/jira/browse/HIVE-9670
             Project: Hive
          Issue Type: Sub-task
            Reporter: Sergio Peña
            Assignee: Sergio Peña


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.
