Class OrcFileMetadata

java.lang.Object

org.apache.hadoop.hive.llap.io.metadata.OrcFileMetadata

All Implemented Interfaces:

ConsumerFileMetadata, org.apache.orc.FileMetadata

public final class OrcFileMetadata
extends Object
implements org.apache.orc.FileMetadata, ConsumerFileMetadata

ORC file metadata. Currently contains some duplicate info due to how different parts of ORC use different info. Ideally we would get rid of protobuf structs in code beyond reading, or instead use protobuf structs everywhere instead of the mix of things like now.
