----------------------------
Summary: OrcMapreduceRecordReader support building ReaderImpl
using incoming OrcTail
Key: ORC-746
URL: https://issues.apache.org/jira/browse/ORC-746
Project: ORC
Issue Type: Improvement
Reporter: Yang Jie
SPARK-33449 discusses adding file meta cache mechanism for Spark SQL to reduce
data reading and speed up query.
For the scenarios that need to use OrcMapreduceRecordReader, we hope to add an
interface to support passing an existing OrcTail or FileMetadata to OrcFile and
use this instance to build ReaderImpl.
