Summary: Migrate to ProtobufRpcEngine2
Key: HIVE-27506
URL: https://issues.apache.org/jira/browse/HIVE-27506
Project: Hive
Issue Type: Task
Components: llap
Reporter: Ashok Kumar
Hadoop has moved over from protobu 2.5.0 to hadoop shaded protobuf.
It has created
[ProtobufRpcEngine2|https://github.com/apache/hadoop/blob/release-3.3.4-RC1/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/ProtobufRpcEngine2.java]
for this purpose.
Hive llap still uses
[ProtobufRpcEngine|https://github.com/apache/hadoop/blob/release-3.3.4-RC1/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/ProtobufRpcEngine.java]
which is meant for protobuf 2.5.0 e.g
[Ref#|https://github.com/apache/hive/blob/bd02abc9eba3aa0cd3701b26d9169130551a12ef/llap-common/src/java/org/apache/hadoop/hive/llap/LlapUtil.java#L267]
This Jira is to update Hive llap codebase to use ProtobufRpcEngine2
