Summary: Migrate from ProtobufRpcEngine to ProtobufRpcEngine2
Key: HDDS-13951
URL: https://issues.apache.org/jira/browse/HDDS-13951
Project: Apache Ozone
Issue Type: Improvement
Reporter: Huang Guan Hao
Assignee: Huang Guan Hao
I found that we have TODO comments indicating in
[https://github.com/rich7420/ozone/blob/f9facd848ae52781badb468f741017bd8a68af11/hadoop-ozone/common/src/main/java/org/apache/hadoop/ozone/om/ha/OMFailoverProxyProviderBase.java#L134]
. It says we should migrate from `ProtobufRpcEngine` to `ProtobufRpcEngine2`
after upgrading to Protobuf 3.x. Since we're already on Protobuf 3.25.8 and
Hadoop 3.4.2, it would be good to complete this migration.
Current Status: * Hadoop 3.4.2 includes `ProtobufRpcEngine2` (verified in
`hadoop-common-3.4.2.jar`)
* Protobuf 3.25.8 is in use
* Still using `ProtobufRpcEngine` in ~20+ places
