类 OrcShimV230

java.lang.Object

org.apache.flink.orc.shim.OrcShimV200

org.apache.flink.orc.shim.OrcShimV210

org.apache.flink.orc.shim.OrcShimV230

所有已实现的接口:

Serializable, OrcShim<org.apache.hadoop.hive.ql.exec.vector.VectorizedRowBatch>

public class OrcShimV230
extends OrcShimV210

Shim orc for Hive version 2.1.0 and upper versions.

After hive 2.3 and later, the orc API is basically stable, so we can call it directly.

Since hive 2.2 not include orc classes, so we can use hive orc 2.3 to read from hive 2.2.
